Unimplemented methods in StylesheetRoot class

[Michael J Conner <mc...@execpc.com>]

Hello,

We had been using another XSL parser to generate the XSL document from an xsl file.
We were able to manipulate the resulting Document object to insert new nodes in a few key locations, and were planning on using this technique to perform a sort of conditional include, based on business rules within our application. 

However, we plan to the Java version of Xalan, and have run into a problem. While the StylesheetRoot class is a decendant of Document, most of the methods seem to throw unimplemented exceptions.  Is this something which will soon be changed, or is this part of the intended design?  Is there some way to manipulate the Nodes of a StylesheetRoot?

More generally, is there a better approach to take to solve this problem?  It occurs to
me that we could pre-process the xsl, since it is, itself, an XML document. But I'm concerned that this would be somewhat slow.


Thanks,

PS. Is there a more appropriate resource to which I should be directing my question?
