Problems Faced:
We need to use a method to propagate the HTML tag attributes like height, width etc across the converters to the final HTML converter. This is different from the query-string which propagates using the Iri() .. waldi suggested to use this, but is unclear ATM. Need to discuss further.
Another not so elegant method would be to use a special character in the qs, to mark that these key:value pairs will have to be stripped from the query and put as HTML attributes in the final converter stage.
Discuss further.
