right, of course you can use processing instructions

<?context-command ...?>

given that this feature is enabled (\setupXMLprocessing[command=yes])

or you can tex an attribute

\def\xxxx{....}
\disableXML\scantokens\expandafter{\xxxx}\enableXML

but i agree with simon that this is not what attributes are for; actually, 
this is also what is wrong with svg
