Yes a catalog was definitely needed. On the whole I'd slapped it all
together pretty quickly (and poorly).

I've added a catalog now: 

  http://www.w3.org/XML/2005/01/xml-id/test-suite.xml

I also constructed an XSLT (1.0) stylesheet that can drive the tests
(if the xml:id implementation in question can inject the IDs before
running the processor, of course).

| The main difference from the OASIS format is the use of id elements to specify
| the expected output rather than output files. Each scenario would contain a list
| of zero or more id elements. The value of each such element is the value that
| should be reported by a conformant processor. For instance the above test case
| requires that the processor normalize the white space in the original attribute.
| Order matters here. Processors would be required to generate the exact values
| shown in the exact order.
|
| This makes writing a test driver fairly straight-forward. Load the catalog file.
| Iterate through all the tests. For each input file, list all the ID-type
| attributes in the order they appear and compare to the id elements in the
| scenario element.
|
| There are only eleven test cases currently, so it shouldn't be too hard to put
| this together. I'll try make a first pass on the problem this weekend, and then
| we can edit it or play with the markup as people think appropriate.

Thanks. I also added a "result" element, used by the XSLT harness.

| Here are some things I'm not sure of yet:
|
| 1. Should we assume people will install the files on their local file systems or
| should we just point to the test cases with absolute URLs to the W3C site?

Does it matter?

| 2. Do we list only xml:id values or all ID-type attribute values?

I think I've listed all ID values.

| 3. The test-case element should have a features attribute to identify optional
| features required to pass a particular test case that not all implementations
| may support. For instance, some of the test suites require schema support or XML
| 1.1 support, which not all processors will supply. Reporters should list these
| tests as skipped or "not applicable" rather than failed. What is the list of
| such features?

Only 'schema' and 'xml11' occur to me.

| 4. Would the working group like to define a standard output format for
| submitting test results? I think the XInclude working group has a nice format we
| could borrow if so.

I've coded up a format in my runtests stylesheet, please tell me what
you think.

Thank you!
