I don't think there was a technical reason. As I recall ,  the group felt it was not required and specification was restricted..

Subject:        [DFDL-WG] rationale for only allowing pattern facet on xs:string        type
Sent by:        dfdl-wg-bounces@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).
