I don't think so, no.

Dan Connolly and TimBL wrote up an *excellent* note about this topic
(and some other related ones);


Streaming XML is a good example of where this would be a bad idea.
If a processor hit the stream mid stride, it would have missed the
namespace declarations.  The same issue applies to processing on small
devices, where the beginning of larger documents may be discarded from
memory before the document is finished processing.
