Hi,
Techniques H57 ("Using language attributes on the html element") and
H58 ("Using language attributes to identify changes in the human
language") are silent on language subtags. However, the BenToWeb
project found unexpected behaviour when language subtags were used.
At least one screen reader (JAWS 8.0, both with Internet Explorer 6
and Firefox 2) ignored the language markup and used its default
language for speech synthesis when a language subcode was used on the
'html' element.
We developed several test cases with language subcodes. With JAWS set
to American English, sc3.1.1_l1_006 [1] (American English),
sc3.1.1_l1_007 [2] (British English) and sc3.1.1_l1_008 [3] (language
code for British English) are read as American English; with JAWS set
to British English, sc3.1.1_l1_006, sc3.1.1_l1_007 and sc3.1.1_l1_008
are all read as British English. So it seems that language subcodes
can't be relied on by web developers.
