[0] XSEM (September 2001) [1] The XML Scripture Encoding Model (XSEM) was intended to do and be the same thing OSIS is attempting, but didn’t gather a critical mass of followers. It is superior to OSIS in some ways. [2] Yes [4] Difficult [5] Poor, currently limited to a GBF-to-XSEM converter as far as I know. [6] Initially embraced by SIL, but now SIL is using USX instead of OSIS or XSEM based on some ease of software development issues related to the recursive definitions used in XSEM. Although XSEM is technically superior to OSIS in many respects, lack of actual use by software developers and working linguists makes this a dubious standard. [7] Since I don’t know of anyone besides me who wrote any significant software to use XSEM, and I will be concentrating on where I perceive the practical advantages (USFX, USX, and USFM) in the future, this is probably not a good encoding to use.

Maybe. The documentation is a little unclear in this area, but XSEM may suffer the same defect as OSIS.
