Claude Warren commented on JENA-839:
------------------------------------
I'll try to build a list of all the interactions that are affected.
My thought on the concat are that it should be an xsd:string as you can
guarantee that hte result of the concat will meet the requirements of the
xsd:normalizedString.
> E_Regex only works with XSDstring.

> Key: JENA-839
> URL: https://issues.apache.org/jira/browse/JENA-839
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ
> Affects Versions: Jena 2.12.1
> Environment: Linux
> Reporter: Claude Warren
> Assignee: Claude Warren
>
> E_Regex eval verifies the argument is a string using:
> {noformat}
> Node arg = NodeFunctions.checkAndGetStringLiteral("REGEX", args.get(0)) ;
> {noformat}
> NodeFunctions.checkAndGetStringLiteral verifies that if the nodevalue is not
> null and is an XSDstring by the following statement:
> {noformat}
> if ( dt != null && !dt.equals(XSDDatatype.XSDstring) )
> throw new ExprEvalException(label + ": Not a string literal: " +
> nv) ;
> {noformat}
> this means that other string types (e.g. XSDnormalizedString) fail.
> I believe that the check should be to check that dt is an instanceof
> XSDBaseStringType.
> I am looking for comment before making the change.
