[jira] Commented: (XERCESJ-962) minInclusive facet validated against lexical space, not value space

Sandy Gao commented on XERCESJ-962:
-----------------------------------

It seems the questions is whether the lexical representations of facet values are required to be valid wrt to the base type.

The base type should be used to convert the lexical value to the actual schema value, and the base type won't know how to do the conversion if the input isn't in its lexical space, so I believe the current Xerces behavior is correct.

> 5 is from the value space of "integer". It appears that xerces is checking the Value '5' against the lexical space of the derived type.

> A value from the - value space-  of the {base type definition}.
