Oh wow, here we are full circle.

@matmarex mentioned there is a weakly followed coding convention of naming parameters containing html with the prefix html-, i guess we could do some special casing to look for that if the the params to TemplateProcessor are provided as an array literal (similar to some of the magic Database methods get). Or even try and get the list of html parameters by reading the mustache file. Not exactly the most compelling of ideas as it would be pretty limited.
