conversion from docbook: missing releaseinfo information

[vinc17fr]

With pandoc 2.9.1.1 (and previous versions) under Debian/unstable, when converting from docbook, the releaseinfo information is missing in the output.

Example manual.xml docbook file:

<?xml version="1.0"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
  "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd">
<book>

<bookinfo>
<title>Title</title>
<author>
<firstname>Firstname</firstname><surname>Lastname</surname>
</author>
<releaseinfo>1.17</releaseinfo>
</bookinfo>

<para>Text.</para>

</book>

But with

pandoc -s -f docbook manual.xml -t html
pandoc -s -f docbook manual.xml -t texinfo

there is no mention of 1.17 in the output.

OK, I've added parsing of releaseinfo as metadata, which you can confirm using

pandoc -s -f docbook -t native

However, it won't appear in html or texinfo output unless you use a custom template that includes the releaseinfo variable somewhere.
