[xsl] What is the relationship between transforming, mapping, and filtering?

Hi Folks,

How do you define those terms? Are they synonymous? Is one a subset of another?

By "mapping" I mean populating XML instances of one data standard with data 
from another data standard. For example, I am currently mapping a military air 
navigation data standard to a civilian air navigation data standard.

By "filtering" I mean performing actions on data such as redacting, fuzzing, 
and zeroing. One could think of these actions as mapping: if I fuzz a lat/long 
location, I am essentially mapping the location to another location.

By "transforming" I mean all the kinds of things you can do with XSLT.

Is filtering a subset of mapping? Is mapping a subset of transforming?
