Your current select expression tells the processor to select all 'define'
nodes that are descendants of the document element.  To select just
descendants of the context node, do:

<xsl:apply-templates select=".//define[@name=current()/@name]" mode="def"/>

(This doesn't address optimization of course--this search pattern can be
quite expensive.)
