+Apart from HTML, \SpecialChar LyX
+ can generate documents in the DocBook XML vocabulary.
+ With versions 2.3 and before, only select templates could be used to generate
+ DocBook documents (only version 4).
+ Starting with \SpecialChar LyX
+ 2.4, most \SpecialChar LyX
+ layouts can generate valid DocBook documents (only
+ version 5).
+ This feature is built into \SpecialChar LyX
+ and does not require the use of external tools.

+The result is that the DocBook output can be customized and extended in
+ exactly the same way \SpecialChar LaTeX
+ output can be customized and extended: through layout
+ files and modules.

+Math output is performed mostly in MathML (the major exception being constructio

+ All formulae are also available in raw \SpecialChar TeX

+Bibliographies and citations are implemented, including with an external
+ BibTeX file.
+ Bibliography entries are not prerendered when the detailed information
+ are available, but rather output with the standard DocBook constructs.
+ The external DocBook processor is expected to handle the rendering of entries.
