It was to prevent confusion between XML schema pattern facet and DFDL text
number and text calendar patterns.

Subject: [DFDL-WG] rationale for only allowing pattern facet on
xs:string type
Sent by: dfdl-wg-bounces at ogf.org
The pattern facet is allowed on all types in XML Schema.
DFDL says the XSDL pattern facet is for xs:string type elements only.
What is the rationale for this restriction?
We are encountering many constraints in format specs that are using XML
Schema regular expressions, where those regex are applied to numeric types
(e.g., xs:decimal for lattitude and longitude).
