we get a NullPointerException for any <redirect-to> that gets called in our
subsitemap. i presume this is because a <generate type="file"> has been
called, but we must use the "cocoon:" protocol in order to divide our
pipeline into a main pipe which calls down into page-specific fragments. no
"actual" generation has happened before the redirect.
is this NPE fixable? if not, how else can we organize our pipelines into
per-page sitemaps? resources don't work because they can't be called from a
subsitemap.
using cocoon 2.1.2

<map:match pattern="xsl/*/*/*.html">
