DTF has a very simple and powerful way of transforming your property data at resolution time that allows you to extract/append/encode/escape your data so that it can be used by another tag in a different way. The syntax for the property transformation is the following:

 
 ${property_name:transformer:arguments for transformer}
 

All of the existing Transformers should have their DTF Documentation created and be under the "Transformers" documentation group so they can easily be looked up.
