Subject: Springer Nature Journals layout: is this change safe?
To: LyX Developers <[email protected]>
Hi all,
Following a report from Scott, I tried to improve the situation for
exporting Springer Nature Journals to DocBook. The last few patches improve
the situation quite a bit (and they should be safe to go in 2.5.x).
There are two stubborn issues: algorithm floats and appendices.
Unless I implement something specific to parse algorithms, the example will
never work as is (the ERT starting with \begin{algorithmic}[1]) — there is
nothing standard in DocBook for algorithms, I don't think I'll go
this route unless there is a real need.
I wrote a patch for appendices (in attachment), but I do not want to push
without review. The current layout considers appendices as BackMatter, but
they are really section titles. With this change, the DocBook output for
appendices is correct, but I'm not sure exactly how much the change impacts
the rest of LyX (apart from the UI). Without this, I cannot make appendices
generate valid DocBook (well, unless we refactor the UI part from the
handling part of categories: sections have a really different code path
than the other styles in DocBook due to its hierarchical nature).
What do you think? Maybe I missed something?

Subject: [PATCH] DocBook: in Springer Nature Journals, mention the impossibility of handling appendices.
The problem (as seen from the example): the appendix should close the previous section (the `<db:appendix>` tag cannot be within the current `<db:section>`). Plus, the `<db:appendix>` tag must enclose the whole appendix, while here we only have access to the appendix title.
