Justification:<\/b> Incorrect use of EPSG code as 'EPSG:4326' in ISO 19128, and as 'EPSG4326' or '4326' in ISO\/TS 19139.
Proposal:<\/b> Correct use was 'EPSG::4326', as specified in OGC 6-023r1 Definition identifier URNs in OGC namespace, which was superseded by OGC 07-092r3 for the URN form, which has itself been superseded by OGC 09-048r3 Name type specification - definitions - part 1 - basic name for the http URI form which as of June 2010 became the preferred form for OGC identifiers.
Hence, identifiers for EPSG definitions are
http:\/\/www.opengis.net\/def\/{type}\/EPSG\/0\/{code} where {type} is crs, cs, datum, etc.
