Robert,

Patches for these bugs is welcome.

Currently GDALRasterAttributeTables can be read from
imagine format, and read/saved in XML (.aux.xml) format
when "pam" support is enabled.

It does seem natural to implement write support for imagine
format, but this wasn't a pressing issue for the project things
were initially implemented for.   I can't give any real timeline
for further work on this area.  Well, I will try and incorporate
any fixes you provide quickly of course.

Best regards,
