[Geoapi-devel] Modeling associations in ISO TC/211 standards

[Bryce L Nordgren]

GeoAPIers,

I think the following problem with the PDF document has been resolved.

What I'm looking for (Martin, Simone and others) is a warm fuzzy feeling
that my statement of the java generics issue is correct, as I'm redo-ing
the existing 19123 interfaces based on it.  I think that the geometry
interfaces may have to be looked at too.

On the up side, if I'm right we can always just use the java 1.4 version of
the library until the silly 1.5 semantics get sorted out. :)
