Ehhh... what ?

	1.1.  Intentionally Strict Processing

	   This specification intentionally defines strict parsing and
	   serialisation behaviours using step-by-step algorithms; the only
	   error handling defined is to fail the operation altogether.

Since the only failure is total failure, why or even how would you go
about postponing it ?
