Does that all work properly? The template has
<XDtEjbRef:forAllEjbRefs>
<XDtClass:ifDoesntHaveClassTag tagName="ejb:ejb-ref"
paramName="view-type">
<ejb-ref>
<ejb-ref-name><XDtEjb:ejbRefName/></ejb-ref-name>
<ejb-ref-type><XDtEjb:beanType/></ejb-ref-type>
<home><XDtEjbHome:homeInterface type="remote"/></home>
<remote><XDtEjbIntf:componentInterface
type="remote"/></remote>
<ejb-link><XDtClass:classTagValue tagName="ejb:ejb-ref"
paramName="ejb-name"/></ejb-link>
</ejb-ref>
</XDtClass:ifDoesntHaveClassTag>
</XDtEjbRef:forAllEjbRefs>
but the XDtEjbRef:forAllEjbRefs appears to switch (i.e. set current class)
to each of the classes at the other end of the reference; so won't the
<XDtClass:ifDoesntHaveClassTag> and <XDtClass:classTagValue> be looking at
the wrong class? What if the target class doesn't have an ejb:ejb-ref
tag?

What does the ejb-link mean? The DTD says "The ejb-link element is used
in the ejb-ref element to specify that an EJB reference is linked to
another enterprise bean in the ejb-jar file.", which isn't all that
helpful. Is it to help it set the target jndi name of the target when
deploying?

What's this bit doing? The template has
<XDtClass:forAllClassTags tagName="ejb:ejb-external-ref">
<XDtClass:ifDoesntHaveClassTag tagName="ejb:ejb-external-ref"
paramName="view-type">
...
</XDtClass:ifDoesntHaveClassTag>
<XDtClass:ifHasClassTag tagName="ejb:ejb-ref" paramName="view-type">
Now, while <XDtEjbRef:forAllEjbRefs> appears to switch to the target
classes, <XDtClass:forAllClassTags> certainly shouldn't. So this appears
to be checking for an ejb:ejb-ref tag in the same class as the
ejb:ejb-external-ref - why should there be both? Shouldn't all the
necessary parameters be on the ejb:ejb-external-ref tag?
