Nothing untoward in there, but using that data and adding a single debug 
statement pointed me to the problem.

Being a second-generation computer programmer (my father started in the 
trade in 1961, I started programming in 1971), I have long relied on the 
"printf method of debugging", so I added at the top of the modify template:

     <xsl:message><xsl:value-of select="name(.)"/></xsl:message>

The problem is happening the *second* time around because of the above 
statement.  I saw *two* element names exposed before the problem was triggered.

Add <xsl:with-param name="curnode" select="$curnode"/> (or with whatever 
you need for the argument) to your nested <xsl:apply-templates/> and it 
will work because you are passing a node for the second invocation.

The first time around, $curnode was just fine ... it was the second time 
around that you weren't passing a value and the defaulted empty string was 
being used.

I hope this helps.
