Rahsad, any objection to push the patches upstream?

No objection. please push changes from upstream

Good to know - could this be pushed upstream also, to keep things cleaner?

Yes. I think it would be good to have this option as it clears lintian error. add tinyxml as a dep for OTB and add OTB_USE_EXTERNAL_TINYXML=ON to cmake settings

#1 seems better in fact. I suppose this would involve rebuilding the whole toolchain
based on GDAL, or is this compiled as a plugin?

openjpeg can be built as a plugin for gdal[1].

could be cool if there can be a extra package called gdal-plugin-openjpeg which can be a dependency for OTB

All the best.
