Ah, then why not init the attribute each time and use the shorter \XMLop 
(own parameter):

   \defineXMLargument [title] [label=] {\chapter[\XMLop{label}]}

best combine this with:

   \setuphead[chapter][expansion=yes]

An unreadable alternative (just illustrating expansion is):

\defineXMLenvironmentpush [title] [label=]
   {}
   {\expanded{\chapter[\XMLop{label}]{\XMLflush{title}}}}
