I don't understand your concern about the language, because the values of
the 'requested-attributes' is of the type 1setOfKeyword. A value with a
'keyword' type must
be in en-us language and ascii character set. In the above example the
response would
in details looks like,
value-tag=1setOfKeyword
name-length=0x0014
name='requested-attributes'
value-length=0x000c
value='printer-info'
value-tag=1setOfKeyword
name-length=0x0000
value-length=0x0010
value='printer-location'
