Hi John,
It is definitely illegal. Just have a look at the Spec:
A NMTOKEN must contain at least one NameChar (
http://www.w3.org/TR/REC-xml#NT-Nmtoken )
Your Attribute List declaration is also lacking of a DefaultDecl (
http://www.w3.org/TR/REC-xml#NT-DefaultDecl )
But it is possible to construct a definition for what (I think) you want
to say:
<!ATTLIST pangolin
color (green|blue|red) #IMPLIED
>
With this a non specified attribute is possible.
Greetings,
Patrick
