Consider the following MWE:

\startxmlsetups xml:demo:base
  \xmlsetsetup{#1}{tag}{xml:demo:tag}
\stopxmlsetups
\xmlregisterdocumentsetup{demo}{xml:demo:base}
\startxmlsetups xml:demo:tag
  %\doif{\xmlnamespace{#1}}{o}{NameSpaceO:}
  \xmlflush{#1}
\stopxmlsetups
\starttext
\startbuffer[test]
<?xml version="1.0"?>
<root xmlns="NameSpaceA"
      xmlns:o="NameSpaceO">
  <tag>text</tag> <o:tag>text</o:tag>
</root>
\stopbuffer
\xmlprocessbuffer{demo}{test}{}
\stoptext

My questions:

- Is there a good way to have a separate XML setup for each XML namespace?

- Alternatively, one has to do the distinction within the same XML setup. In this case, how do we get the complete namespace? (In this example: "NameSpaceA" and "NameSpaceO")

Thanks in advance for your help!
