Start Validating input output transformation

Validating input output transformation

Each of these allies have their own perimeters which may or may not trust ours. As noted in the Introduction, we trust nothing and nobody.

This is one of those compartmentalising by trust value issues I mentioned.

In suggesting that users are untrusted, we imply that everything else is trusted. Users are just the most obvious untrusted source of input since they are known strangers over which we have no control.

A “guard” is a negative predicate or term in an XPath that filters out unwanted cases.

Schematron requires fewer guard constructs than many other languages.

Therefore, the XSLT programmer can perform the validation only as a second step, following the transformation.

XSLT 2.0 specifies the features of a schema-aware (SA) XSLT 2.0 processor that allows exactly this.

This is because in a pattern, the lexically first rule whose context matches a node is the one that fires.

A pattern is a big case statement of if/then/else if/then chain.

Connected to this perimeter are separately guarded (and very suspicious looking) “allies” including the Model/Database and Filesystem.
