Your <peculiar> element has mixed content, and XSD 1.0 gives you no way =
to
constrain the text that may appear in an element with mixed content.

You can do this using assertions in XSD 1.1:

<xs:element name="peculiar">
  <xs:complexType mixed="true">
    ...
    <xs:assert test="matches(text(), '\p{IsGreek}+')"/>

Implemented in Saxon 9.1.

"2"
