Subject:
[sca-assembly] NEW ISSUE: (1.2) Why
do global channel references use "//". Should be single "/"
to be consistent with URI syntax

Title:  Why do global channel references use
"//"? Should be single "/" 

to be consistent with URI syntax

Target: Assembly 1.2 WD 03

Description:

While we call the types of @source and @target attributes on components

of type anyURI, why are the references to global domain channels using
"//"?

In URI-land, the use of "//" after the scheme and colon (as in

"http://", "ftp://") indicates a hierarchical scheme
(which, at the 

moment, this is not). In addition, even if we were to treat these URIs

as hierarchical references, access to the "root" of the current

hierarchy is always done with a single "/" character, rather
than two of 

them.

In XPath syntax, the "//" operates as syntactic shorthand for
all 

descendants.

Current use of "//" appears to be syntactically unnecessary,
conveys 

intent that isn't meant, and is inconsistent with typical use of a 

single "/" character to access the root.

Proposal:

Change the "//" used to reference global domain channels to a
single "/".
