Re: Reading the values of elements in a complex parame

  -- Write the dynamic XML to a known document path.
  -- Include the path in the XSL.
  -- Call Xalan.
  -- Xalan imports, parses and uses the tree.

  Is this a normal and appropriate use of xsl:include?


xsl:include (and import) are just for including parts of the stylesheet.
I think you want document() which is for including XML documents at
run time. If you are (for example) running a local http server you can
arrange to include any dynamically generated content you want with
sonething like
select="document('http://localhost://cgi-bin/myscript?param1=a')
where the cgi-bin script myscript takes the parameter and returns
whatever xml needs returning. If you can generate the "dynamic" XMl
before XSLT starts you don't even need a server you can do as you
suggest above, just generate the XML in advance at a known location then 
select="document(file:///path/to/the/xml')"
