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 "/".
