Well krita does since 1.5, and next version of Gimp will. But, both of them 
might not be the main customers of your library, at least for Krita, which has 
already its own facilities for open raster.

No, not yet. I think we are aiming at support for RDF/XMP, with something like 
that:

<layer ... metadata="data/layer1metadata.xmp" />
and
<image ... metadata="data/imagemetadata.rdf" />

Unless we want to have more than one metadata file per-layer, and do something 
like:
<layer ...>
  <metadata type="xmp" file="data/layer1metadata.xmp" />
  <metadata type="rdf" file="data/layer1metadata.rdf" />
</layer>

Sounds reasonable.

Oups, no it's good, my fault.
