Oxygen XML Forum

Hello,

I was recently asked a question about the autocomplete suggestions in oXygen Editor text mode:
- where does oXygen take the suggestions for languages for xml:lang definition from?
I read that DITA-OT is not case sensitive - why is there option de-DE and not de-de?
Is there any way to edit that language list?
Can anyone give me some more information about this?

regards,
Justyna

Hi Justyna,

The DITA 1.3 standard does not specify a hardcoded set of values for xml:lang:
https://www.oxygenxml.com/dita/1.3/spec ... llang.html
Those particular values you get in the content completion window are provided by an Oxygen specific DITA framework customization file located in:
OXYGEN_INSTALL_DIR/frameworks/dita/resources/cc_config.xml
Usually such configuration files are not edited directly, someone could for example create an extension of the DITA framework customization which provides their own version of the cc_config.xml which would suit their team better:

About this question you had:

I read that DITA-OT is not case sensitive - why is there option de-DE and not de-de?

Yes, the publishing engine should not interpret the values in a case sensitive manner.
There are various standards like:
https://www.rfc-editor.org/rfc/bcp/bcp47.txt
which seem to treat "Language-Region" by capitalizing the region name and this is from what I encountered common.
But indeed, in the specs above it says:

At all times, language tags and their subtags, including private use
and extensions, are to be treated as case insensitive: there exist
conventions for the capitalization of some of the subtags, but these
MUST NOT be taken to carry meaning.

Thus, the tag "mn-Cyrl-MN" is not distinct from "MN-cYRL-mn" or "mN-
cYrL-Mn" (or any other combination), and each of these variations
