+ TPM_STRUCT_VER
+
+ This indicates the version of the structure.
+
+ Version 1.2 deprecates the use of this structure in all other structures. The structure is not
+ deprecated as many of the structures that contain this structure are not deprecated.
+
+ The rationale behind keeping this structure and adding the new version structure is that in
+ version 1.1 this structure was in use for two purposes. The first was to indicate the structure
+ version, and in that mode the revMajor and revMinor were supposed to be set to 0. The second use
+ was in TPM_GetCapability and the structure would then return the correct revMajor and
+ revMinor. This use model caused problems in keeping track of when the revs were or were not set
+ and how software used the information. Version 1.2 went to structure tags. Some structures did not
+ change and the TPM_STRUCT_VER is still in use. To avoid the problems from 1.1 this structure now
+ is a fixed value and only remains for backwards compatibility. Structure versioning comes from the
+ tag on the structure and the TPM_GetCapability response for TPM versioning uses TPM_VERSION.
