I would like to know the reasoning for prohibiting criticality flags. The semantics "if you do not understand X then you do not understand this signature" appears to me to be essential. For example X might be 'check that this document has not subsequently been revoked and superceeded using a (specified) OCSP type mechanism'. This type of semantics is essential if signed documents are to be used to represent signed negotiable documents such as a letter of credit of a bill of lading. Phill
