[Zope] Is DTML a bastardized form of XML, or valid XML?

[Kevin Howe]

Hi,

just wondering if DTML is actually a valid form of XML, or a bastardized
version of XML created specifically for ZOPE. I've done a little reasearch
on XML, and I it seems like DTML tags such as:

<dtml-var "...">    or

<dtml-if "...">
    ...
<dtml-else>
    ...
</dtml-if>

aren't really valid XML forms. The following would make more sense:

<dtml-var expr="..."/>    or

<dtml-if expr="...">
    ...
    <dtml-else>
        ...
    </dtml-else>
    ...
</dtml-if>

Anyone care to enlighten me?

Thanks,
kh
