Simplify the document
Document structure and editorial changes

3. Main Technical Changes
Signature policy attribute made optional for Basic Electronic Signature (BES)
BES = CMS + signing certificate attribute (i.e. hash+id of cert).
Backward compatibility with older versions ( and RFC 3126) provided by Explicit Policy-based Electronic Signature (EPES)
EPES = BES+ signature-policy-identifier attribute
On generation conformance to either BES or EPES is required
Two new optional attributes for attribute cert refs
id-aa-ets-attrCertificateRefs
id-aa-ets-attrRefsRevocationRefs
