I'd like some feedback on this before proceeding.  One of the most frequent
customization requests I get is to display this or that MARC field or subfield
in the OPAC.  Usually this would have to be done by customizing the relevant
XSLT stylesheet (MARC21slim2OPACResults.xsl and MARC21slim2OPACDetail.xsl are
the two I usually work with.  However, for sites where access to the server
level is restricted or where local customizations are not allowed, this won't
work.  I'm thinking of creating a syspref to allow a site to specify a remote
server location for the XSLT stylesheets.  That way, sites could maintain and
modify a file with local customizations, without requiring any server access.

Trying to analyze the code in XSLT.pm, it looks like I could only allow
specifying a path, not a filename.  Both details and results files would have
to be in place on the remote server, and retain the identical filenames as
currently used.

Right now, I'm only looking at OPAC XSLT, but the same logic could be extended
to staff XSLT files as well.  I think they would have to be stored in the same
location as the OPAC ones, so maybe only one syspref should be created for
both.

Discussion?  Potential problems?
