If I'm reading correctly (assuming 'entities' for 'attributes'), I don't
think that this is a very good approach.  Instead of

  <p>xxxx &myDynamicMacro; xxx</p>

I'd recommend something like

  <p>xxxx <aml:dynamicMacro a="bbbb"/> xxx</p>

or even

  <p>xxxx <?aml macro a="bbb"?> xxx</p>

They do the same thing, but play nicely with existing tools (i.e.
someone could easily do the substitution with XSL if they wanted to) and
don't complicate your data model as badly.


All the best,


David
