Technically, just the term "form" without more clues is slightly unclear.
 You do not know if it's the xml:lang= structure or the xml:lang="" empty
string structure.  And that's where the confusion stemmed from.  "form"
alone is unclear.  Your expecting someone to see "" and know we are talking
about the empty string structure.  An improvement would be to reword
explicitly with this:

The xml:lang="" form, where an empty string is provided in lang, represents
the absence of a language identifier.
