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

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> Best regards, Ganesh
