How will the authors of OGC Standards that have chosen not to use CRS Well Known Text to communicate properties of Coordinate Reference Systems update their standards to support new/updated capabilities defined in OGC Topic 2 and ISO 19111? #85
FWIW, not difficult for WCS. The interface between coverages and CRSs have been kept very simple: just need some identifier - currently only URLs are allowed, but this could be relaxed, without bw compatibility issues, to hold references to WKT defs or even contain them verbatim in the same coverage document. Just a little help from the CRS WKT folks is required to get all phrasing correct.
