Re: [earlywarning] What problem is ATOCA trying to address?

Apologies for the slight digression. Not to be contentious, but CAP is
only part of the application payload solution. Other countries are using
other encodings instead of CAP (such as SMS) or are using additional
application solutions in addition to CAP (such as GeoRSS or GeoSMS).

Something also to be aware of WRT CAP. The OASIS EM TC has defined a set
of requirements for an enhanced OASIS "where" model (geographic) that will
be encoded as a GML application schema. The plan is to be consistent with
the PIDF-LO geodetic GML schema as well as GeoRSS GML. This work adds
additional geometries and other elements such as multipoints. These
requirements were provided by the CAP implementation community and will be
incorporated (perhaps by extension) in CAP 2.0 and future revisions of
EDXL.
