When testing out the limits of namespaces, I created two tests to demonstrate that the "middle dot" (·) is acceptable within a namespace name, but not as the first character. In the test that I expect to fail, this is the error I get:

[info] - test_namespaceSpecialChars2 *** FAILED ***

Would it be possible to get a more descriptive error (or at least a Schema Definition Error so it can be matched in a tdml test)? I was also trying to figure out if DFDL-506 is at all related to this.

The test is namespaceSpecialChars2 in:
