Transformation approach

XML transformations written as plain and straightforward Scheme programs

Use of a small set of AST traversal functions

Relies on mirrors of both the source and the target XML languages

Authoring and transformation steps
- A document is authored in Scheme and LAML relative to a specific XML language
  - Needs an XML DTD of the source language
- The AST of the source document is established
  - ASTs are returned by the mirror functions of the source language
- The AST of the source document is transformed to an AST in the target language
  - The transformation is activated by an action procedure of one of the top-level forms
- If necessary, the target document is linearized in XML syntax
  - Raw or pretty printed
