If metadata does not contain XMP properties belonging to the EXIFAux scheme, the method returns null.

If the metadata does not have EXIF Auxiliary XMP properties, and you need to add such properties, create a new instance of the com.accusoft.imagegear.formats.xmp.exifaux.ImGearEXIFAuxXMPMetadata class, pass it to this method, and then add XMP properties using corresponding properties of the com.accusoft.imagegear.formats.xmp.exifaux.ImGearEXIFAuxXMPMetadata class.

If you need to remove EXIF Auxiliary XMP schema properties from the metadata, set this value to null.
