John,

Generally speaking the driver documents are the place to find out details
like this:

   http://www.gdal.org/frmt_nitf.html
   http://www.gdal.org/frmt_nitf_advanced.html

Of note, there is also support for capturing text segements which
are encoded in the TEXT metadata domain.  It is also possible to grep
on "Metadata" in the source code for the driver in question to get a sense
of any that weren't documented.  When I do that I notice that RPCs are
also returned in the RPC domain, and ICHIP data in main metadata domain.

Well, you can open the file yourself.  GDAL does not try and present the
raw header data through metadata.
