as is often the case, asking a question in a public forum usually helps one answer their own question... couple of things I was doing wrong and/or could do differently. First, bug in my xslt. I was asking for match="id(oid)" instead of the correct match="id($oid)" that still requires having the id as an attribute defined in the dtd. when properly defined, that works. alternative is to use xsl:key and key() function. this was probably not the right forum to post this in the first place. sorry for the bandwidth. cheers!

trying to sort something out...
XSLT (through XPath, I guess (http://www.w3.org/TR/xpath#function-id) has an id() function that, if I understand the docs correctly, will return the node (or nodeset, if the parameter is a nodeset of id strings) from the document that has the given id value.
Great!
Now, one problem. For that to work, apparently the id value needs to be declared as an attribute of ID type in a DTD. Bummer. See note in http://www.w3.org/TR/xslt#section-Embedding-Stylesheets.
Ok, so I tried that, but Oxygen doesn't seem to find it.
Does Oxygen (and/or XSLT in general, to your knowledge) support the id() function in XSLT? Can it work with an ID-typed element?
My problem is that I am presented with an XML document that makes heavy use of IDREF type elements and I'm trying to transform them in XSLT. Perhaps there's a better way or I'm doing something wrong. Will post to xml dev list if this comes back negative.
attached are my (hackish! just trying stuff out) xml, xsd, and xsl files I've been using to test. Note that in the xsl
<xsl:variable name="onode" select="id(oid)"/> ids:<xsl:value-of select="$onode"/>
"onode" is null (well, empty nodeset.)
Thanks, Linus
