You could change the key to be all of the @val attributes joined using a

match="replaceWith" use="string-join((ancestor::* except
searchReplace)/@val, '-')"

then you should be able to call using the much shorter:

key('blah', string-join((modelic,sdc,chapnum,....), ','), $doc)

which if they are in document order anyway then just:

key('blah', string-join(*, ','), $doc)

Ironically 'throwaway' code often hangs around for long time...
