The AddOutputFilterByTypeDirective was depreciated in Apache 2.1
Here is a conf snippet to declare the filter to mod_filter. you may also want to enable it for 'text/xml'.
FilterDeclare XSLT
FilterProvider XSLT xslt_filter resp=Content-Type $application/xml
FilterChain XSLT
# for debugging
FilterTrace XSLT 1
for details on mod_filter see: [Apache Mod filter][1].
