Subject: ISSUE 254: Names of channels should allow "/", should be declared asURIs....

The only concern I have about this issue/proposal is that its seems to imply that there is a relationship between global channels that is somehow understood by the SCA Runtime. As currently defined there are no architectural relationships between global channels, which is why I think we originally settled on a NCname. Changing this to a URI might allow a user to imply some relationship between global channels, but an SCA Runtime will not be aware of such relationships.

[sca-assembly] NEW ISSUE: (1.2) Names of channels should allow "/", should be declared as URIs....


Title: Names of channels should allow "/" character, and should be
declared as URIs....

Target: Assembly 1.2 WD 03


As declared in section 5.7, the name of a channel is defined as an
NCName.  However, NCNames do not allow for "/".

All references to channels use the type "xs:anyURI", but ironically, we
don't allow for "/" in the names of channels.  Further, there's
potentially a discrepancy between a URI and NCNames. To be consistent,
we should use xs:anyURI for both the definition & the references.

While this capability may not add much for private/local channels, for
the purposes! of global domain channels, this facilitates a natural
hierarchy of global domain channels following the well-accepted practice
of using "/" to indicate hierarchy.


Change the type of the "@name" attribute on channel to be of type
xs:anyURI. Note the caveat that this must conform to the "path-rootless"
production from part 3.3 of RFC 3986.  In other words, it cannot start
with a scheme, nor a "/".
