Not me - conversion work of legacy data routinely involves pulling documents to
pieces, working on a fragment (such as a table) then putting it all back
together. A language such as OmniMark will allow you to find fragments without
parsing the data around it - under those circumstances, what is proposed is
unduly restrictive.
