XSD/e validates only the commonly-used subset of the XML Schema facets,
as documented in these Appendices:

https://codesynthesis.com/projects/xsde/documentation/cxx/parser/guide/#A

https://codesynthesis.com/projects/xsde/documentation/cxx/serializer/guide/#A

For decimal, these are min/maxExclusive and min/maxInclusive.

You can, however, provide a custom parser and/or serializer implementation
for your type that performs any additional validation, as described in
"Customizing Parsers and Serializers":
