Or using a filesystem (XSL 1.0):
<xsl:apply-templates
select="document(concat($path-to, $identifier))"/>
Is the problem that filesystems are not good enough yet? (I don't have a
problem with win or linux, but I am not huge)
Do people really feel a file based system is more difficult to manage
(what with versioning - CVS/SVN, and checkout.., stage versions for
dev/qa/cert/live.., wherever/whatever) than a relational database hacked
to accomodate (roundtrip) XML?
