The version number (v1.0.1) has been chosen to align with the W3C IMSC v1.0.1 Recommendation. EBU-TT-D version 1.0.1 adds the following two extensions from IMSC 1.0.1: #fillLineGap and #activeArea. By clarifying the required processor behaviour in the presence of unrecognised attributes compatibility with other TTML profiles is improved.
