This WebMake Perl library provides the xsl WebMake tag, allowing you to
apply the named XSL stylesheet to the named XML data, rendering the output in
place of the tag.
The named items should be defined as WebMake content or template items of
format text/xml, in order to use dependency information correctly.
XSL parameters may be passed in using attributes.
Note that the Perl module XML::Sablotron is required.
