Re: docbook and xml:lang attribute

Hello,

All the issues you describe are not caused by our product XMLmind XML 
Editor. They are caused by the DocBook XSL Stylesheets, our products 
uses to convert DocBook to HTML.

XMLmind Software does not develop or maintain the DocBook XSL 
Stylesheets. Therefore it's difficult for us to help you.

Project page: https://github.com/docbook/xslt10-stylesheets

Notes:

- When you convert your index.xml to a *single* HTML page, the DocBook 
XSL Stylesheets generate:
---
<body...>
<div class="book" lang="nl">
---

Moreover the DocBook XSL Stylesheets use the xml:lang attributes to 
translate the generated text (Contents, Chapter, Index) to nl 
(Inhoudsopgave, Hoofdstuk, Register).

- When you convert your index.xml to *multiple* HTML pages, the DocBook 
XSL Stylesheets just use the xml:lang attributes to translate the 
generated text (Contents, Chapter, Index) to nl (Inhoudsopgave, 
Hoofdstuk, Register). They do NOT add lang="nl" anywhere in the 
generated HTML pages.

Yes, this clearly looks like a bug.

- Your index.xml and mainpage.xml had *severe* *structural* *errors*. 
Before being able to convert these to HTML using XMLmind XML Editor, I 
had to fix all the structural errors.

Please note that XMLmind XML Editor is not meant to be "usable" on XML 
documents  having structural errors. Moreover  XMLmind XML Editor is not 
designed to make it easy fixing this kind of errors. Sorry for that!

Fixed versions of your files attached to this email.
