[jsr-314-open] Old version facelets taglib jars

[Ganesh]

On the MyFaces dev list there are some discussions about
which versions of facelets taglibs should be allowed
with MyFaces 2.0. Mojarra runs fine with old facelets
taglibs, but MyFaces 2.0 beta currently insists on 
a taglib version=2.0. So, what does the EG say: Is
a JSF 2.0 compatible implementation required to
refuse old version facelets taglibs? Here's the relevant
part of the spec:

<xsd:simpleType name="facelet-taglib-versionType">
   <xsd:annotation>
      A-100 JavaServer Faces Specification • March 2009
      <xsd:documentation>
         This type contains the recognized versions of
         facelet-taglib supported.
      </xsd:documentation>
   </xsd:annotation>
   <xsd:restriction base="xsd:token">
      <xsd:enumeration value="2.0"/>
   </xsd:restriction>
</xsd:simpleType>
