Base "TRAX" API for XSLT transformers. This API borrows many structural notions from SAX, such as the way error handling and external entity resolution are handled, although it does not reuse the corresponding SAX classes. To use XSLT transformers:

• Start with TransformerFactory.newInstance();
• Then you may wish to configure that factory through its features and properties. This includes modifying the way errors are handled and URIs are resolved.
• Then you have several options for how to perform the XSLT transformations. One generic option is to ask the factory for a Transformer and then use Transformer.transform() to pull input text onto output text.
• Alternatively, most factories support flexible integration with SAX event streams. You can cast such factories to a SAXTransformerFactory and perform either push or pull mode transformations.

The OutputKeys class holds constants that can be used to configure output properties used with Result objects, as if they were specified in xslt:output attributes in the stylesheet specifying the transform.

The Templates class accomodates the notion of "compiled" transforms.
