Thanks for your help. I can use that, but why is this sort of double-checking necessary here?

\startxmlsetups xml:test
	\xmlsetsetup{#1}{*}{-}
	\xmlsetsetup{#1}{doc|element}{xml:*}	
\stopxmlsetups

\xmlregisterdocumentsetup{test}{xml:test}

\startxmlsetups xml:doc
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:element
1 \xmldoifelse{#1}{.[@class and contains(@class,'abc')]}{Yes}{No} \par
2 \xmldoifelse{#1}{.[@class and find(@class,"abc")]}{Yes}{No} \par
3 \xmldoifelse{#1}{.[True and contains(@class,'abc')]}{Yes}{No} \par % runs, but no match
4 \xmldoifelse{#1}{.[True and find(@class,"abc")]}{Yes}{No} \par % run, but no match
% 5 \xmldoifelse{#1}{.[contains(@class,'abc')]}{Yes}{No} \par % causes an error
% 6 \xmldoifelse{#1}{.[find(@class,"abc")]}{Yes}{No} \par % causes an error

\stopxmlsetups

\startxmlsetups xml:whatever
Yes
\stopxmlsetups

\startbuffer[test]
<?xml version="1.0" encoding="UTF-8"?>
<doc>
<element class="abcdefg">Yes</element>
<element>No</element>
</doc>
\stopbuffer

\starttext

\xmlprocessbuffer{test}{test}{}

\stoptext
