[gentoo-dev] Useflags: xsl vs xslt

["René Neumann" <lists@necoro.eu>]

Dear all,

I noticed, that there is a global useflag 'xsl', with one of those
bleh-descriptions "Enables XSL support"

There is exactly one user of it: php -- to pull in libxslt.

Now there is also the local useflag xslt (used by three other packages)
for enabling xslt support (by pulling in libxslt).

My questions now are:

* Is there a real difference between them? As far as I can see XSL is a
superset of XSLT, but it's somewhat fuzzy.
* Should 'xsl' remain a global useflag?
* Should php remain 'xsl' or go to 'xslt'?
* When building a new package with optional XSLT-support: Should I use
'xsl' or 'xslt'.

Thanks,
René
