The data translator API

There are only two custom functions in the data translator API, but both are required. The functions in the data translator API differ from the functions in the main JavaScript API in three ways:

They are not methods of the dreamweaver, dom, or site object.
They are significant only in the context of data translator files. That is, Dreamweaver automatically calls the translateMarkup() function if it is defined in a data translator file, whereas in any other extension file a function named translateMarkup() acts like a user-defined function—you have to call it explicitly.
You are responsible for writing the body of each function and returning a value, if required. This is the opposite of how the functions in the main API work: those you call and pass arguments to, and Dreamweaver generates return values, if any. Here Dreamweaver calls the functions and passes arguments to them, and you generate return values, if any.
