It is now invalid to write an an EL expression inside view-id!

                 Key: JBSEAM-3741
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3741
             Project: Seam
          Issue Type: Bug
    Affects Versions: 2.1.0.SP1
            Reporter: Francisco Jose Peredo Noguez

I am hitting this issue JBIDE-3248, at first I thougth it was an incompatiblity problem between JBoss Tools 2.1.2, and Seam 2.1.x, but now I think it is an error in http://jboss.com/products/seam/pages-2.1.xsd.

In pages-2.1.xsd we have this code (that didnt exist in 2.0):

    <xs:simpleType name="view-id">
        <xs:restriction base="xs:string">
            <xs:pattern value="(/.*)|\*"/>

That is limiting view-id by preventing it from using EL expressions inside it, but EL expression do work inside view-id:

<navigation from-action="#{someEntityHome.persist}">
     <rule if-outcome="persisted" if="#{not empty someEntityFrom}">
         <redirect view-id="{#someEntityFrom}"/>
        <rule if-outcome="persisted" if="#{empty someEntityFrom}">
         <redirect view-id="/Crud/SomeEntityList.xhtml"/>

The line  <redirect view-id="{#someEntityFrom}"/> is being reported as an error, but it is perfectly fine. I think the <xs:pattern value="(/.*)|\*"/> specified for view-id in pages-2.1.xsd is an error.
