I agree that 1995 GeoTIFF 1.0 is the naming / title of legacy GeoTIFF standard. IMHO, this OGC GeoTIFF specification should make it clear about this verison / revision as early as Introduction (which is just informative) and Scope (or in a sub-section of clause 1: This version. Clause 2 confoamnce should only address conformance statements for this version, and address Annex A. The sentence "Any discrepancies between this specification and the community GeoTIFF standard identified in Chapter 3 should be brought to the attention of the OGC® for resolution" has nothing to do with conformance clause, and seems to me a weird statement in a standard. This is a message that may be setn to reviweers for internal SWG review, or public RFC ... but should be suppressed. Having said that, I agree with the proposal to name this OGC GeoTIFF version 1.1 (in order to avoid any ambiguity with 1995 GeoTIFF 1.0). In addition the major/minor revision tags are 1.1, so seems better (IMHO) to align the version numbering, unless there is any objection.
Unless any objection, I propose to delete the last paragraph of clause 2: This version 1.0 of the OGC® GeoTIFF standard is a formalized version of the GeoTIFF specification currently in common use. Any discrepancies between this specification and the community GeoTIFF standard identified in Chapter 3 should be brought to the attention of the OGC® for resolution. (For the reasons provided above)

"1. Scope""mentions "It should therefore be backward compatible with the 1.0 version, both for coordinate reference systems based on EPSG register codes, or user-defined coordinate reference systems." and "2. Conformance" mentions "This version 1.0 of the OGC® GeoTIFF standard is a formalized version of the GeoTIFF specification currently in common use. Any discrepancies between this specification and the community GeoTIFF standard identified in Chapter 3 should be brought to the attention of the OGC® for resolution."
This wil be confusing for readers without full background. In 1) (and in many/most other places of the new document), 1.0 refers to the 1995 spec. In 2) to the current OGC spec.
