Hello Simone

I'm trying to align GeographicMetadataFormat more closely along "GML in JPEG
2000" specification, but it seems to me that a strict match is not pratical
given IIOMetadataFormat intentional restrictions. You told us that you were
working on such a IIOMetadataFormat on your side as well. Would it be possible
to point us to a URL or send it by email please? Our implementation is available
on Geotools SVN since May 27, but I don't know if it is mergeable with your work
and how far we can tolerate departure from the "GML in JPEG 2000" specification.
Can we try to work on a common GeographicMetadataFormat?

Examples of departure compared to "GML in JPEG 2000":

- IIOMetadata doesn't support namespace. Do we agree to drop "gml:" prefix?

- The way "GML in JPEG 2000" lists "axisNames" elements is illegal in
IIOMetadataFormat. Do we agree to regroup them in a "axes" parent element? Same
for "offsetVector".

- From a look to other IIOMetadataFormat implementations in J2SE, values are
usually stored as attributes, while "GML" usually stores them as elements. Do we
replace:

   <Envelope>
     <lowerCorner>5 6</lowerCorder>
     <upperCorner>7 8</upperCorder>
   </Envelope>

(GML way) by (more IIOMetadata way):

   <Envelope lowerCorner="5 6" upperCorner="7 8"/>

given that the later seems to fits better with IIOMetadata API?

                Martin
