uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pElements	Array of GML data.
uNumOfElem	The size of the GML data array.

Comments

GML data contains the Geography Markup Language (GML) information for a single or multiple codestream. The primary role of GML in relation to JPEG 2000 is to provide an XML encoding of the metadata necessary to make the JPEG document a georeferenced or geographic image.
