The DITA OT documents this. The parameters when dealing with the DITA OT directly are: ftr, hdf, and hdr (corresponding to the settings that we provide in our dialog with similar names).
See:
http://dita-ot.sourceforge.net/1.5.4/readme/dita-ot_ant_properties.html
Unfortunately I think that documentation is a bit misleading as it states “well-formed XML file”. While that is technically true, it isn't very specific. What this file should really usually contain is XHTML that will be valid where it is inserted.
FTR is inserted at the end of the
element in the XHTML, before the closing tag.HDF is inserted at the end of the element in the XHTML, before the closing tag.
HDR is inserted at the start of the element in the XHTML, after the opening tag.
