<para>This is technical reference documentation for the DocBook XSL
Stylesheets; it documents (some of) the parameters, templates, and
other elements of the stylesheets.</para>

<para>This reference describes the templates and parameters relevant
to formatting EBNF markup.</para>

<para>This is not intended to be <quote>user</quote> documentation.
It is provided for developers writing customization layers for the
stylesheets, and for anyone who's interested in <quote>how it
works</quote>.</para>

<para>Although I am trying to be thorough, this documentation is known
to be incomplete. Don't forget to read the source, too :-)</para>
