This is a huge selling point in terms of simplicity, and also gets points in the "plays well with others" category... However-- Murray (or someone), educate me. Here's a quote from the XPointer CR: <quote> XPointer supports addressing into the internal structures of XML documents. It allows for examination of a document's hierarchical structure and choice of its internal parts based on various properties, such as element types, attribute values, character content, and relative position. In particular, it provides for specific reference to elements, character strings, and other parts of XML documents, whether or not they bear an explicit ID attribute. </quote> Is XPointer so oriented to tree structures that it is subtoptimal for XTM's more graph-like structures? OTOH, could the "XTMQL document" of which you speak be a reference implemenation, leaving optimizations up to vendors? S. ===== <?
