Seen in the light of to what it responds, this is an amazing statement. Perhaps I misread it, but it suggests to me this thought: XML representation excels in the clarity and explicitness of structure; system architecture establishes important large-scale structures; XML representation can help to establish very clearly the relationships between document content and system structure - between document and large context, that is - and to align content items with items of system architecture.

I was not intending to suggest that a systems architecture has to be based on XML in order to be considered "good".

I do think that uniformity of data model and data representation across a system help enormously in ensuring the architectural coherence of the system, and an architecture based on end-to-end XML can help to achieve that goal.
