int_daisy_mixedContentNormalizer
Transformer documentation: int_daisy_mixedContentNormalizer
Transformer Purpose
- Normalize mixed content models as a step towards making the text nodes of an xml document suitable for a DTB context.
- Optionally add synchronization marker attributes that indicate positions in the XML document that would server well as SMIL text targets.
Input Requirements
Any XML document. The normalization process can be specialized and optimized for particular namespaces; however, the routine can be applied to arbitrary namespaces as well, albeit with non-predictable results.
Encounters of namespaces unrecognized to the normalizer will yield a warning: support for new namespaces are given an XML configuration file, see extended configurability
Output
On success
An XML document with any mixed content siblings normalized by means of inserted "wrapper" elements.
On error
On error, this transformer will send a fatal message, then throw an exception and abort.

Extended configurability
Customizing the DOM-based normalizers behavior
