Generating XHTML with navigation

The toolkit ships with several varieties of XHTML output, each of which follows roughly the same path through the processing pipeline. All XHTML builds begin with the same call to the preprocess routine, after which they generate XHTML files and then branch to create navigation files.

Once the preprocess runs, XHTML based builds each run a common series of Ant targets. Navigation may be created before or after this set of common routines.
