1.7 Versioning and Capability Negotiation

There is no capability negotiation based on versioning in this protocol. There are several fields that provide version information. The Registry Policy Message Syntax (section 2.2.1) contains a version which is a fixed value. An ADM-Based Policy Description Message can contain an ADM Conditional Directive described in section 2.2.2.1.1 that compares the current platform against a version constant that represents platform releases. The ADMX-Based Policy Description Message schema described in Appendix B: Full XML Schemas (section 7) contains informational revision and schemaVersion attributes.
