Re formats:
when we write specs referencing formats (rarely done anyway, for good reasons) 
we do not repeat)the format specs. We rather set referencesto the definition 
that is "somewhere out there", such as TIFF. A notable exception is NetCDF which 
was brought into OGC's curation by the NetCDF proponents, and GeoSciML. In both 
cases, the original maintainers have become OGC members where they continue 
doing so, just embedded into OGC infrastructure now.

What we do in the coverage field, though, is describing how coverage 
constituents map to the particular format elements (eg, coverage bounding box 
coordinates -> GeoTIFF tags). This is under way for GeoTIFF, NetCDF, JPEG2000 
(meaning drafts are existing, and in part in the pipeline for adoption).
