A good while ago Robert Strandh approached me about a project idea. Namely that of a form of unified document processor, that could be used for any document format. His argument was that basically any new document format boils down to a question of syntax, while everything else about a document would get reimplemented anew for each new format syntax, generating a huge amount of wasted effort. What if there was a unified processing model that a syntax parser could be plugged on top of?
