DocBook contains a large number of XML elements from which we only use a subset.
Be aware that XML (not just DocBook XML) has two special
characters that cannot be used literally in text:
< (the opening angle bracket) and
& (the ampersand sign). Whenever you need
to use those two characters literally, you have to use entities,
like in this example:
Alternatively, you can wrap any content that contains characters that cannot be used literally within CDATA containers, like this:
<![CDATA[(content that might contain characters illegal in XML)]]>
This makes sense particularly for larger pieces of code within
<programlisting> or similar containers.
We structure documentation using nested
book as DocBook defines it would
look like this:
<book> <chapter> <section> <section> ... </section> </section> </chapter> <appendix> <section> ... </section> </appendix> </book>
