folks might want to create templates using pure XML, using custom tags (mapping namespaces/elements to function calls) and the ${foo} notation for expressions.

So rather than a custom parser as we have now for SSP, we can have something which parsers the XML and transforms elements based on their namespaces (and looks for ${foo} expressions too).

We could then process things like this...

{code}

...

...
${something}
...


{code}

which would translate to the equivalent of this in SSP

{code}


...

...
${something}
...


{code}
