## New Features
  - Option `--schema` lets you specify an URN to a DocBook 5 schema that is to
    be used for validation. Will be ignored when validating Docbbok4 documents.
  - `DOCBOOK5_STYLE_URI`, `DOCBOOK5_STYLE_URI`, and `DOCBOOK4_STYLE_URI` may now
    also point to a local file. If the URN begins with the prefix "file://",
    it will not be resolved via xmlcatalog, but rather taken as is (minus
    "file://").
  - Add conversion options to online-docs:
    * `--db5todb4`: converts DocBook 5 sources to a DocBook 4 bigfile
    * `--db5todb4nh`: converts DocBook 5 sources to a DocBook 4 bigfile without
      a DOCTYPE declaration
    * `--dbtonovdoc`: converts DocBook 4/5 to Novdoc

## Misc
  - Do not set `-nocs`, hurts us when building Arabic (related: issue [#108])
  - Avoid adding version attribute on all elements (commit 3a273d5)
