    + code to read this & generate UIs is in:
	+ DTD: xmlscript/dtd/dialog.dtd
	+ xmlscript/source/xmldlg_imexp/imp_share.hxx, line 674
	+ xmlscript/source/misc/unoservices.cxx
		xmlscript/source/xmlflat_imexp/xmlbas_import.cxx (?)
		"com.sun.star.comp.xmlscript.XMLBasicImporter"
	+ the dialog piece seems separate ?
		"importDialogModel" ...
	+ cf. the interesting test code ...
	+ cd xmlscript/test
	  dmake
	  ../unxlngi6.pro/bin/imexp /opt/OOInstall ./test.xml
	    + generates & renders a dialog ...

	+ This code has ~all we need to get a simple impl.
	    + compatibility wrappers [!]

    // first create model:
    Reference< container::XNameContainer > xModel( xContext->getServiceManager()->createInstanceWithContext(
	OUString( RTL_CONSTASCII_USTRINGPARAM( "com.sun.star.awt.UnoControlDialogModel" ) ), xContext ), UNO_QUERY );
    // NB. xmldlg_addfunc.cxx not xmldlg_import.cxx [!?] ;-)
    ::xmlscript::importDialogModel( ::xmlscript::createInputStream( bytes ),
				    xModel, xContext );

    // second create view of model:
    Reference< awt::XControl > xDlg( xMSF->createInstance(
	OUString(RTL_CONSTASCII_USTRINGPARAM( "com.sun.star.awt.UnoControlDialog" ) ) ), UNO_QUERY );
    xDlg->setModel( Reference< awt::XControlModel >::query( xModel ) );

    // third - associate toolkit / peer ...
    Reference< awt::XToolkit> xToolkit( xMSF->createInstance(
	OUString( RTL_CONSTASCII_USTRINGPARAM( "com.sun.star.awt.ExtToolkit" ) ) ), UNO_QUERY );
    xDlg->createPeer( xToolkit, 0 );

    // fourth - execute [ nasty ... ]

** Basic dialog editor:

    + basctl/source/dlged/dlged.cxx
	+ dialog editor (?)
    + basctl/source/basicide/basobj3.cxx
    + basctl/source/basicide/basides3.cxx
	+ BasicIDEShell:CreateDlgWin ...


** FIXME:
	+ createPeer - when called is always passed
	  the toplevel [ it seems ... ]
	+ we need to pass a container instead ...
		+ or have some separate hint / method ?
		+ or call the 'setChild' inside the model
		  construction bits ? [!?]

UnoControlContainer::addingControl:
	+ only caller to 'setContext'
		+ sets the 'Parent' for peers ...

Dialog is an UnoControlContainer ...
	+ hmm ...
	+ 'XControlContainer'
		+ perhaps just what we need ... [!]
	+ our VBox should be one ...

	+ Other things: tab widgets are 'UnoControlContainers' ...
		+ finally remembered: xml foo ...
		+


	+ FIXME: it -seems- that we don't store
		 much hierarchy in the model [ any ? ]
		+ UnoControlModel -> ?

	+ UnoControlDialogModel - has an XNameContainer ...
		+ but ... only the UnoControl-Dialog-Model has this ...


	+ Wow - even the percieved hierarchy:
		+ 'exportDialogModel'
			+ achieved by 'getElementNames'
				-> flat set of names ... [urgh]

	+ So - we need to add more structure:
		+ XNameContainers ...
			+ that we insert into [!?]
		+ we also need to retain order for packing.

	+ need a list of sillies to reverse / revert (?) ...

	+ back-compat:
		+ kill bogus nesting eg. radiogroup ...
			[ have a group/tag instead - or hierarchical names ? ]
		+ ditto for 'titledbox' ...
		+ menulists - seem rather unrelated / bogus anyway.
		+ Add into toplevel & child ...

    + copy Dialog bits into unocontrolcontainer.cxx ...
	+ re-using unocontrolcontainer ...


** FIXME:
    + we need property introspection on the awt widgets:
	+ but they have no property interfaces [!] -
	    interestingly the UnoControl's don't either
	    only the UnoControlModel foo ...
	+ unocontrols.cxx:
	    Uno
    + source/helper/property.cxx
	+ has all the type information ...
	+ but no information on what properties are
	  valid for a type ... - implicit in the UnoControlModel's
	  code ...
	    + ImplGetPropertyInfos ...

    + add to vclxwindow.cxx:
	+ inc/toolkit/helper/property.hxx
	+ 'getProperties' static ...

** It seems that things like UnoControlComboBoxModel are missing
   some derived properties: EchoChar (etc.)
    UnoControlDateFieldModel - missing ... EchoChar too (?) - deliberate ?
    + query these ... [!?]

layout container - start child 'combobox'
   missing property 46 (EchoChar)
   missing property 48 (HardLineBreaks)
   missing property 12 (HScroll)
   missing property 104 (LineEndFormat)
   missing property 10 (MultiLine)
   missing property 13 (VScroll)

    + add regression test:
	+ count number of properties ...


TODO:
	add 'XPropertySetInfo' to VCLXWindow:
	    + trivial to implement :-)
	    + hook it to Ricardo's parser ... [!] :-)

* xmlscript
	+ xmldlg_import.cxx -
	+ xml_helper/xml_impctx.cxx - foo ...


* plan:
	+ hard-code container hooks into the xmlscript/ parser ...
	+ create a layout object in toolkit/
		+ populate it with good things ...

	+ coupling to toolkit - widget instantiation: how ...
		+ ComponentInfos
			+ vclxtoolkit.cxx:
		+ has a 'hook function' for 'fnSvtCreateWindow'
		  for SVT widgets :-) [ grotesque ;-]
			+ [ wow - fetched by dlopen! ;-]

	+ A little app - a-la solver: using awt (?)
		+ XMessageBoxFactory ...
		+ XToolkit:
			+ CreateWindow ...
		+ ** how does the xml code generate these guys ? **

	+ what APIs does the xmlimporter use ? not 'createWindow' seemingly.

+ existing xml import uses: property bag a -lot-:
	Reference< beans::XPropertySet > xProps(
	        _pImport->_xDialogModel, UNO_QUERY_THROW );
	* we do _xDialogModel->insertByName (new any<XControlModel>())
		+ to build hierarchy ( cf. ~ControlImportContext )

	DialogImport:
		css::uno::Reference< css::container::XNameContainer > _xDialogModel;

	Reference< container::XNameContainer > xModel( xContext->getServiceManager()->createInstanceWithContext(
			OUString( RTL_CONSTASCII_USTRINGPARAM( "com.sun.star.awt.UnoControlDialogModel" ) ), xContext ), UNO_QUERY );

	toolkit/source/controls/dialogcontrol.cxx
		+ UnoControlButtonModel (eg.)
		+ service 'UnoControlModel' ...

	+ poke at 'titledbox' or 'radiogroup' to see how containment works there ...
		+ how will child widget properties work ?
		+ bug with a 'vbox' inside a 'titledbox' ...
	+ titledbox - acts as a container (interesting)
		- offsetting child positions
	+ how will pseudo-containers eg. "radiogroup" cope ?

	+ propose new syntax: [ with child properties a-la glade ]:

	<hbox id="baa" flange="true">
		<child padding="0" expand="false" fill="false">
			<radio id="foo" value="..."/>
		</child>
		<radio id="foo" value="..."/>
	</hbox>

	+ if 'child' element omitted - default properties used ...
	+ if multiple elements in same 'child' set: all have the same props.
