Although that syntax actually only applies to FORMAL public identifiers
in SGML. Not to XML public identifiers. XML only specifies Public
identifier syntax by a range of characters, and the (non normative) SGML
declaration for XML specifies FORMAL NO. In other words XML public
identifiers don't have to use the  
"-//ECC, Inc//DTD myDTD version //EN" syntax.

In particular it is quite legal (and even perhaps sensible) in XML to
use a URI as the public identifier, although this wouldn't be legal in
most SGML dialects where the PUBLIC identifier is normally specified as
being an FPI.
