Their own format with the profile, temperature and pressure blobs in
base64 encoded binary blob. I have one sample attached. SOB if you
want to include that.

I would guess that XSLT cannot be used to handle the blobs. So we
should include those in blob elements and implement the parsing in C.
(Base64 decode, and read floats, chars or ints from the buffer,
depending on the blob.)
