Hi Wolfgang,
OK, here is a minimal example:
file test.xml:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE test [
<!ELEMENT document (section)>
<!ELEMENT section (#PCDATA)>
]>
<document>
<section title="First">
<p>This is <quotation>an</quotation> xml file.</p>
</section>
</document>
file testenvironment.tex
\usemodule[xtag-ent]
\defineXMLenvironment[document]
{\starttext}
{\stoptext}
\defineXMLenvironment[section]
{\section{\XMLpar{section}{title}{}}}
{}
\defineXMLenvironment[quotation]
{\quotation\bgroup}
{\egroup}
When I process with mkii, I get the expected output. Processing with
texexec --lua --env=testenvironment test.xml
gives me the first line (here it's not an entire page) I described!

I tried to translate this into the "new" mechanism and thought it
should read like so:
\startxmlsetups xml:mysetups
\xmlsetsetup{\xmldocument}{text:p|section|quotation}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:mysetups}
\startxmlsetups xml:p
\xmlflush{#1}\endgraf
\stopxmlsetups
\startxmlsetups xml:quotation
\quotation{\xmlflush{#1}}
\stopxmlsetups
\startxmlsetups xml:section
\section{\xmlatt{#1}{section}{title}}
\stopxmlsetups
\starttext
\xmlprocess{main}{test.xml}{}
\stoptext
But then, I only get "invalid xml file" in the output.

OK, I'll keep that in mind. Thanks for your help, Wolfgang!
