that is a tag/length that isn't needed as far as I know
and needs to be stripped so our internal code works.
but other implementation will maybe not have such an
tl-header before the real content.
They do have, by definition. That's what the TLV in
SC_FILE_EF_LINEAR_VARIABLE_TLV stands for. The code is not complete
(complete handling would also handle all variants of
{CYCLIC,LINEAR_{FIXED,VARIABLE}}{,_TLV}) but at least it's correct.
that's not quite correct. According to iso 7816-4 the first byte
in a TLV record is the tag byte followed by 1-3 length bytes
(if the first length byte is 0xff two additional bytes are used
to specify the length of the value part as a big-endian uint_16).
Cheers,
