Re: [xsl] grouping after filtering (follow on question: about meucheunmethod)

[Joerg Heinicke <joerg dot heinicke at gmx dot de>]

There, where you use the key() function, the Muenchian Method itself, 
add a filter, similar to the following:

<xsl:apply-templates select="book[@author='author2'][generate-id() = 
generate-id(key('books', concat(author, '::', type)))]"/>
