   - The model [[m prime]] results from applying well-defined transforms, alterations, procedures over [[m]].
     - These transformations, in order, are said to form a [[path]] between [[m]] and [[m prime]].
     - More than one path might link [[m]] and [[m prime]]. Intermediate steps are valid models. 
+    - Transformations are modeled as having attributes like [[cost]], [[feasibility]], [[probability]], [[pros]], [[cons]] as evaluated by a diverse community of modelers.
