I completely agree. The DOM is not "the" API for all XML standards, it is
meant to be a foundation upon other W3C APIs can be built. The DOM
extensions for individual specs might be trivial, e.g. the XSLT people might
want to simply define a method such as [off the top of my head]
transformNode(Node input, Node output, Node stylesheet) so that everyone
implementing XSLT in a DOM-compatible system uses the same names. At the
other extreme is SVG, which is defining a whole set of DOM-compatible
interfaces to expose the higher-level semantics of SVG. XPath (either the
WG or the user community) is free to do likewise.
The DOM working group would much rather be a source of advice on how to make
APIs that are DOM-compatible, platform neutral, vendor neutral, etc. than to
be the ultimate standardization authority for XML APIs.
On the other hand, if there are problems in DOM Level 2 that impede an
implementation of XPath or a definition of simple XPath extensions, they
should be reported to www-dom@w3.org RIGHT AWAY.
