RE: [ietf-provreg] EPP and wildcards

["Hollenbeck, Scott" <shollenbeck@verisign.com>]

The data type used to define domain names is defined in section 4.2 of the
EPP core protocol draft.  Look for the "<simpleType name="labelType">"
definition; it uses the XML schema "token" data type.  This XML Schema data
type allows use of the "*" character.

However, section 2.1 of the domain draft requires conformance with RFCs 952
and 1123.  These don't allow the "*" character in domain names.  You could
use the EPP core data type to define a schema of your own for domain
searching, but searching as you described isn't supported in the domain
draft.
