                                    urls or the char color attribute that formats the portion in which the
                                    url field is contained.
                                    When we set a char color attribute to the paragraphs item set from the
                                    styles item set, we would have this char color attribute as an attribute
                                    that is spanned over the complete paragraph after xml import due to some
                                    problems in the xml import (using a XCursor on import so it does not know
                                    the paragraphs and can't set char attributes to paragraphs ).

                                    To avoid this, as soon as we try to set a char color attribute from the style
                                    we
                                    1. check if we have at least one url field in this paragraph
                                    2. if we found at least one url field, we span the char color attribute over
                                    all portions that are not url fields and remove the char color attribute
                                    from the paragraphs item set
