Re: Fwd: [xsl] curly braces

You may wish to try the code I sent you on saxonhe-9.2.1.1.

I predict (don't know for sure because you are running a cut down
version of the code) the following

; SystemID: ; Line#: 10; Column#: -1
net.sf.saxon.trans.XPathException: Failed to load document
        at net.sf.saxon.expr.Expression.dynamicError(Expression.java:961)

where Line 10 is

<xsl:variable name="this" as="node()" select="doc('')"/>

Also try by substituting the above with the document function instead
of doc, you may see different behaviour.
