Re: [xml-dev] Basic program structures in XSLT (was: Re: [xml-dev] Data-driven application --> the data is essentially "machine code" to the application, right?)
Most basic?
1. Push versus pull.
2. Event-based programming = template matching descent default
3. XPaths 1.0 location steps, and value-of
4. If and choose
5. Rearranging and repeating things: variables, apply-templates/@select, modes
Not basic: key, function, anything in xpath 2 or 3 but not in xpath 1.
In other words, developers should be trained to first use the distinctive language features before (and instead of) rushing to use generic (I.e. vanilla) functional features.

This provokes a similar but broader question: are there analogous basic
principles for program design which can be used to guide construction of
a transformation in XSLT?The schema or a skeleton of the input xml structures tell you all the types of node you have to handle and the built in rules do (by default) an apply-template for each one.
