Data attributes, with a name; what we read as "the file" will be the
anonymous attribute, IIRC?

It shouldn't be too hard to add a simple check for which attribute is
being requested, I presume - AIUI, the NTFS driver is passed the filename,
then goes and looks it up in the MFT, so implementing this should just be
a matter of splitting the "filename" into the MFT entry's name and the
stream name, then accessing the appropriate attribute rather than always
using the anonymous one?
