xml:lang attributes should only use language identifiers in the format
defined by RFC 1766, which means two-character language codes from ISO
639 among other things.  "EN" or "en" (or "En" or "eN") is correct,
"ENG" is not.

There's also the lang() function that returns true or false for a
match on the current xml:lang value, which could be set by a
containing element.  lang() matches case-insensitively and ignores
country subtags when determining a match.  For example, lang('en')
returns true when the current xml:lang value is "EN", "en", or even
my preferred form: 'en-AU'.
