Support for DOM and other external tree models
In the DOM interface (package
net.sf.saxon.dom) Saxon now has compile-time dependencies on methods that
are only available in DOM level 3, that is, in JDK 1.5 or JAXP 1.3. This puts the DOM package in the same
situation as the XPath package: if you want to use Saxon's DOM interface, you need to use JDK 1.5 or
the JAXP 1.3 package installed over JDK 1.4.
The Saxon code as issued is compiled under JDK 1.4, but using the JAXP 1.3 versions of the JAXP and DOM
interfaces. If you want to recompile the Saxon code (for example to apply patches) then you can either recompile
it under JDK 1.5 (in which case it will only run under JDK 1.5), or you can recompile it under JDK 1.4, in which
case you will need to install the JAXP 1.3 versions of the
JAR files in
%java%/jre/lib/endorsed to ensure that they are chosen in preference to the versions
packaged with the JDK.
In the XOM interface, IDREF attributes are now recognized, so the
idref() function now works
