v4.0.0

Refactor TEI output mode: so far the TEI output mode was only used for docx to TEI conversion. Move the docx-specific functions into a separate module so the TEI output mode becomes usable for other scenarios.

This is a breaking change: docx-imports will stop to work properly after updating. To fix this, you must include the ext-docx.xql module into your resources/odd/configuration.xml or odd/configuration.xml:

<modules>
    ...
    <output mode="tei" odd="docx">
        <module uri="http://www.tei-c.org/tei-simple/xquery/functions/docx" prefix="ext-docx"/>
    </output>
