Validation queue job bug924987-2012-02-01T22-33-57.831Z is finished. The final status was:

All tests succeeded!

Voting does not meet specified criteria. Required: Approve > 1, Disapprove < 1. Got: 1 Approve, 2 Pending.

[Markos Zaharioudakis (markos-za)]

1. Zorba does not support the (optional) namespace nodes and associated sequence types. So, the releted code should be removed.

2. Why do the createSchemaElementType and createSchemaAttributeType have a contentType param? This is not according to the sequence type syntax and should be removed.

3. Just curious: why doesn't the emit() method print out the type using the w3c sequence type syntax?

4. An XQType of USER_DEFINED_KIND (i.e., an instance of the UserDefinedXQType class) represents a sequence type only if the type is atomic. So, in TypeOps::get_type_identifier(), a TypeIdentifier should be created only is the type is atomic; otherwise an error should be thrown (or an assertion triggered).

5. To be complete, the TypeManagerImpl::create_type(const TypeIdentifier& ident) method should also be fixed. It's up to you whether you want to do it or not.

[Markos Zaharioudakis (markos-za)]

review: Needs Fixing

[Till Westmann (tillw)]

1. ok

2. I see your point, but I think that I need information about the content type. Is there a way to get that from the public API? (I looked over the public static context and didn't see something obvious.)

3. Good question. Actually, the type doesn't really reflect the structure of a sequence type. But as it is, it is an extension of the existing on and thus probably compatible.

4. That's interesting. It seems that the schema types also end up there. At least that's how I used it. I had a "as schema-element(...)" declaration and the content type of the ELEMENT_KIND was a USER_DEFINED_KIND.

5. I'll look at that, but first we need to make sure that points 2-4 are clarified.
