Hi helix84, The only reason I'm aware of is that Apache Cocoon (which XMLUI is built on) by default only supported XSLT 1.0 at the point in time when XMLUI was actually developed.
Many of those dependencies you noted are actually default dependencies of Apache Cocoon. Since then, it sounds like Cocoon can be patched/configured to support XSLT 2.0, as least according to this email thread I found (skim to bottom of thread): http://comments.gmane.org/gmane.text.xml.cocoon.user/68284 There's also various pages on the web which detail how to switch Cocoon to use Saxon instead of the default Xalan: http://blog.reverycodes.com/archives/000034.html So, it sounds like the XMLUI would need to update its sitemaps & Cocoon settings to properly support XSLT 2.0. In any case, these seems like it might be a worthwhile change to investigate. I agree, it'd be nice to upgrade XMLUI to support XSLT 2.0. If you are willing to do so, I'd suggest opening a JIRA ticket with this information. That way we can start to track the work, and add notes/hints to that ticket. - Tim On 8/17/2011 9:50 AM, helix84 wrote: > Hello, > > I'm currently doing some customizations in XMLUI and on every step I > find myself using XSLT 1.0 workarounds while it would be much easier > to use XSLT 2.0.
