CORBA24 — IDL format for RepositoryId

Following statement in CORBA V2.3 (06/1999),
P10-39, Chapter 10.6.1, OMG IDL Format concerning
the OMG IDL format for Repository IDs:

>> The RepositoryId consists of three components, separated by
colons, (":")

The first component is the format name, "IDL."

The second component is a list of identifiers, separated by
"/" characters.

These identifiers are arbitrarily long sequences of alpha-
betic, digit, underscore ("_"), hyphen ("-"), and period (".")
characters. Typically, the first identifier is a unique prefix,
and the rest are OMG IDL Identifiers that make up the scoped
name of the definition. <<

There are two issues here:

• Firstly I propose to change >>"IDL."<< into >>"IDL".<<
• Furthermore, I propose be more specific on the definition
  of the Repository Id. The above definition does not
  exclude a RepositoryId in the following style (which
  in my opinion does not make sense and effects inter-
  operability between ORBs): "IDL:/A/B:1.0"
  A regular expression could clarifiy this issue:

Incorporate changes and close issue.
