Patch decimal type

[wandmagic]

Committer Notes

This is a small fix to silence a warning i discovered when compiling the validator for a default JSON in metaschema using metaschema XSLT. a number type cannot have a pattern keyword, because pattern keyword is only for strings.
it is either, a string with a pattern or a number. This pull request assumes that the "number" is the desired type for this Decimal type.
