Hi, The debate about document() and saxon:evaluate should probably be reopened through the angle of the support of XPointer by XSLT/XPath as well. It's a point I have recently submitted [1] to the www-xml-linking-comments@xxxxxx mailing list. If applications using XPointer (such as XLink and XInclude) are developed, it will become necessary to be able to derefence XSLT XPointer values and to retrieve the node-sets they point. When you find in your source document something like: <elt xlink:href="doc.xml#id"... or <elt xlink:href="doc.xml#xpointer(//book[isbn='0836217462'])"... or even <elt xlink:href="#xpointer(//book[isbn='0836217462'])"... it seems quite natural to want to be able to retrieve the node pointed by "@xlink:href". XPointer can be seen as an extra level of granularity added on top of "usual" URIs and using the document() function could seem natural. However, the fact that a XPointer expression equal to "#id" is pointing to the node whose ID is "id" in the current document while document("") is pointing to the current stylesheet could, IMHO, make it quite confusing if we said that the current document() function was to be used with XPointers as an argument. Whatever solution is chosen (using the document() function or adding a new function), the support of XPointer in XSLT/XPath would require supporting variable XPath since XPointer is built on XPath and allowing to write whatever-function(@xlink:href) where @xlink:href="#xpointer(//book[isbn='0836217462'])" is in fact allowing a variable XPath expression.
