[oXygen-user] Schematron template?

Dear <oXygen/> users, The template loaded when I create a new Schematron seems to have changed in version 17 not only with the addition of Schematron Quick Fix capabilities, but also by replacing the default namespace declaration: xmlns="http://purl.oclc.org/dsdl/schematron" with a namespace prefix definition: xmlns:sch="http://purl.oclc.org/dsdl/schematron" so that the Schematron document is now, by default, in no namespace. This isn't a problem (I can live with it or change it, as I prefer), but it makes me wonder why the default behavior was changed. Are there advantages to defaulting to no namespace, instead of to the Schematron namespace? Thanks, David
