constraint
----------------------------------------------------------------------------------------
Key: XERCESJ-1508
URL: https://issues.apache.org/jira/browse/XERCESJ-1508
Project: Xerces2-J
Issue Type: Improvement
Components: XML Schema 1.1 Structures
Affects Versions: 2.11.0
Reporter: Mukul Gandhi
Assignee: Mukul Gandhi
I'm creating this JIRA issue for tracking purpose.
XML Schema 1.1 extends the constraint, "Schema Component Constraint: Element
Declarations Consistent" with following additional clause (numbered 4):
If the {particles} property contains, either directly, indirectly (that is,
within the {particles} property of a contained model group, recursively), or -
implicitly- , two or more element declarations with the same expanded name,
1 ...
2 ...
3 ...
4 All their {type table}s are either all - absent- or else all are present and
- equivalent- .
The equivalence of type tables is defined as follows:
[Definition:] A Type Table T1 is equivalent to a Type Table T2 if and only if
all of the following are true:
1 T1.{alternatives} has the same length as T2.{alternatives} and their
corresponding entries are - equivalent- .
2 T1.{default type definition} and T2.{default type definition} are -
equivalent- .
We implemented this constraint, post Xerces 2.11.0 release.
