Thank you for the reply, your response got me to test a different path.
What I am trying to do is write an extension element that will resolve an XPath statement to a block of XML that will be used to build a different document other than the Result Tree.
What I did different was try my code as a straight forward XSL example to see how the standard output formatter would perform. So if you look at the XML and Style sheet below, I am trying to emit the parameter using the <xsl:copy-of> which seems to work, except for the strange handling of the comments.
Does the whitespace appear in the output as a result of the <xsl:output tag or is the original whitespace in the parameter maintained ??
Do you have any example code or point me to someplace in the Xalan codebase that I can use as an example in my Extension Element. What I want to do is process the Node/RTF (i.e. the result of evaluating an expression) so that it will produce a new Node/RTF that is formatted to include whitespace nodes ??
Thanks John G

Whitespace-only text in most stylesheet elements is not meaningful, by design, and is discarded. Standard workarounds: make it something other than whitespace-only, or enclose it in xsl:text, or play games with xml:space (though that last sometimes has distinctly unexpected and unpleasant interactions with xsl:attribute, so I don't generally recommend it).
