> DocBook comes in a couple of different flavors--including both
|
|
XML and SGML formats. This means that you may use either the SGML
|
|
grammar/rules when adding markup, or you may use the XML grammar/rules.
|
|
Either way you may only use one set of rules throughout your document,
|
|
and you must define which one you are using at the top of your document.

reasons for this including the following:

between their format and DocBook XML.
