       the base URI reference.  If the given <code>uriReference</code> is a
       same-document reference, <code>baseUriReference</code> is used as a
       reference to the current document.

       @param uriReference
       any URI reference.  Backwards-compatible relative URI references starting
       with a scheme component (see RFC&nbsp;2396, Section&nbsp;5.2,
       step&nbsp;3) are not supported; instead, they are interpreted as absolute
       URI references.

       &ldquo;<code>..</code>&rdquo;) within the path of the base URI (except
       for the last, cut-off segment) are processed as suggested by
       RFC&nbsp;2396.  If <FALSE/>, special segments within the path of the base
       URI are treated like ordinary segments.

       @param excessParentSegments
       details how excess special parent segments
       (&ldquo;<code>..</code>&rdquo;) are handled.

       to an absolute URI reference, relative to the given
       <code>baseUriReference</code>; otherwise, <NULL/> is returned.

       controls how a relative URI reference is generated when both

       <code>uriReference</code> (e.g.,
