Not clear if this is fixing a regression or if the format (at least for XML/compact) was always wrong. Thanks.

Not clear if this is fixing a regression or if the format (at > least for XML/compact) was always wrong. I'm on the fence on this. Try removing the SECTION_FLAG_HAS_TYPE from SECTION_ID_FRAME_SIDE_DATA_COMPONENT and SECTION_ID_FRAME_SIDE_DATA_PIECE and the output is broken again for the compact output. So at least compact_print_section_header() may be faulty. I did not investigate much because I'm not familiar with the code. In any case, this change is needed because of the SECTION_FLAG_HAS_VARIABLE_FIELDS addition for side data where the printed fields are not a fixed amount.

That is, if you define the type (as in the current implementation) it looks correct? > In any case, this change is needed because of the > SECTION_FLAG_HAS_VARIABLE_FIELDS addition for side data where the printed > fields are not a fixed amount. Agree.

Without the type, the unexpected line breaks return.
