--------------------------------------
Summary: Assert evaluation fails when using distinct-values
function
Key: XERCESJ-1675
URL: https://issues.apache.org/jira/browse/XERCESJ-1675
Project: Xerces2-J
Issue Type: Bug
Affects Versions: 2.11.0
Reporter: Patrick Gratz
It seems that there is a problem with the usage of the function distinct-values
in xs:assert tests. Validating the following schema-compliant example against
the related schema fails with the error message:
{noformat}
cvc-assertion.3.13.4.1: Assertion evaluation
('count(distinct-values(descendant::node()/@ADMID)) eq
count(descendant::node()[@ADMID])') for element 'mets' with type 'metsType' did
not succeed.
{noformat}
