Contiguous on what domain - the source or the rendering? Provided that you mean the former, I agree. In other words, an XPointer can be expressed as a byte range. Wheras XSL patterns, and CSS selectors and XQL queries can return results that are disjoint (eg, "all the foo elements which are children of bar") > The important question is whether the syntax could be restricted so that > the XPointer parser could know at "compile time" that only a character or > a range matches. In other words, once they have been unified, how do you tell them apart. -- Chris XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
