Hi everybody:

I have been attempting to improve the issues.roundup-tracker.org
scores.  One of the things is reports is that the head tag is missing
a lang attribute. So the page has no indication of the language.

Ok easy enough, add a tal:attributes="lang request/language". However
request/language can be a list, so I ended up with:

  lang="['en_US', 'en']"

not exactly what I was expecting (nor is it valid). It looks like
en_US would need to be en-US (language-region) format to be
valid. 'en' is fine. But an list isn't allowed.

Using:

  tal:attributes="lang python:request.language[-1]"

does generate

  lang="en"

as wanted, but can I guarentee the proper 2 character language subtag
(per BCP47) will be the last in the list? Looking at the headers
sent by the browser:

  Accept-Language: en-US,en;q=0.9

I guess this just happens to work. Appending "?@language=de-DE"
results in request/language beign set to "de-DE" as
expected. Unsetting the languag cookie using "?@language=none" results in

 <head lang>

but I consider this to be an edge case and it is handled properly by
browsers so I am not going to fix it.

Is there a better request variable to use for setting this attribute?
Does anybody have a templating extension for setting the lang attribute?

I would like to add this to all the page templates that we distribute.

Thanks.
