URI format in noNamespaceSchema location
Hi,
It was reported on the xsd-users mailing that Xerces-C++ on
Windows does not like the noNamespaceSchema attribute value
in the form: "file://C:\foo.xsd". The strange thing is that
it accepts "file:/C:\foo.xsd" (without second /). I think
double slash is the correct format. Can somebody explain
what's going on or should I file a bug report?
thanks,
-boris

I believe you are correct per RFC1738. When I was testing this I had
the Visual Studio IDE open and there a link to the build report was
given as "file://c:/...". I thought it got to be right... :-)

Hi Boris,
I think the correct format is file:///C:\foos.xsd (three slashes,
because the server name is not specified). But I never understood
URI/URL/IRI very much, so...

RFC1738 says:
"As a special case, <host> can be the string "localhost" or the empty
string; this is interpreted as `the machine from which the URL is
being interpreted'."
So I would say "file:///C:/foo.xsd" is as "canonical" as
"file://localhost/C:/foo.xsd".

RE: URI format in noNamespaceSchema location

Hmm. I don't think either is correct. According to RFC 1738, the
syntax for a file: URI is file://<host>/<path>. (RFC 1738 is obsolete,
but neither 2396 nor 3986 provides any specific guidance on the file:
scheme, and I don't think they contradict 1738.) Since the only path
separator allowed for URIs is a forward slash, backslashes in Windows
paths should be turned into forward slashes.
If I'm correct in my interpretation, the canonical URI for the file
system path "C:\foo.xsd" is "file://localhost/C:/foo.xsd". Since <host>
will generally be assumed to be "localhost" if omitted, it's probably
safe to use the short form "file:///C:/foo.xsd".
Since there's a lot of confusion and ambiguity about file: URIs, I
tested both forms above with Firefox 2 and IE 7. Both forms worked in
both browsers. However, this is not definitive; both browsers also
accepted the forms with backslashes, though Firefox transformed the
address into the above short form. Whatever form you use, IE turns it
into a local path ("C:\foo.xsd"), which clearly is not a URI.
