Yes, it is possible to restrict NMTOKENS by an enumeration of values in
an attribute. You did it.

Yes, you have restricted the value of the *list* of NMTOKENS to be
"choix1" OR "choix2" OR "choix3". "choix2 choix3" is clearly *not* one
of the 3 valid choices.
Intuitively, the diagnostic of xsdvalid is 100% correct. Now, given the
complexity of the semantics of W3C XML Schema, may be you are right and
there is a bug in xsdvalid. (I'll not attempt to check this. Please ask
experts.)

Pleas consider using what follows which, IMHO, feels much more ``natural'':
---
<xs:simpleType name="TypeChoixEnumere">
<xs:restriction base="xs:NMTOKEN">
<xs:enumeration value="choix1"/>
<xs:enumeration value="choix2"/>
<xs:enumeration value="choix3"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="ChoixEnumereMultipleType">
<xs:restriction>
<xs:simpleType>
<xs:list itemType="TypeChoixEnumere" />
</xs:simpleType>
<xs:minLength value="1" />
</xs:restriction>
</xs:simpleType>
