Just to follow up with this, it appears this a bit of a bug with C2. I
don't know why the normal Cocoon sitemap wasn't working, but for my sitemap
it was a case of a little too much cutting when I cut and pasted the
sitemap: I was missing the pipeline tags. The questionable behavior is
that
Using Cocoon 2.0.2 Tomcat 4.0.4b JBoss 2.4.4 JRE 1.4.0
I have a straight forward sub-site that invokes a simple 1 stage XML to HTML
pipeline. The main xml target of the pipeline is just a list of the real
xml files that are to be processed, eg:
list
filefile-a.xml/file
With care you may be able to do this in a portable way though not with the
document function. The problem I see with asking the file generator to
check dependencies is the overhead of parsing the entire document on every
request.
That's a reasonable idea; one could code the xsl to pick up a

I suspect our case won't apply to you: we drive validation out of the

I beg to differ. The most part of validation is a trivial matter (minimum
lenght of fields, bounds checking, ...) and this should, in my eyes, be
done
on the client: max performance, min hassles for the user (errors are
interactivaley corrected).
It's not the complexity of the validation
(remember, you still must have validation on the backend)
Precisely my original point: since you have to write the server side
validation anyway, do you really want to write both client and server side
validation? I only do so if there is a real performance penalty with the
