Experiences
CAP can contain all situations we tested
Some parts of CAP is not good XML makes it hard to parse, ie
addresses tag
Language-tag is ambiguous, same language can be coded in
different ways
Common Meteorological coding of parameters and event code
needed (Idea create a meteorological profile)
