Since you used <xs:enumeration> you've said "allow only xs:strings whose
value is specifically '\p{Greek}'".  I think you were after the xs:pattern
facet instead, e.g.

<xs:pattern value="\p{IsGreek}*"/>

The "*" in the pattern means "allow any number of Greek characters,
possibly none"; without it you're allowing only a single character.  You
also might consider \p{IsGreek}+ to require at least one character.
