I guess it would be better to allow constructs as:

<dtml-var "table('main','col')">
   <dtml-var "font('standard')">Some text</dtml-var> 
</dtml-var>

Where 'table' and 'font' are PythonScripts that return the implicit blocks passed to them (these blocks may have a default variable name in the expression's namespaces) enclosed by the correspondent html blocks, with the format ('main, 'standard') mapped to html attributes/values using some dictionaries. This could help to separate logic and presentation in dtml code with a minor syntax addition.
