Error handling

[jesper-sjovall]

A question that we not yet has cover is how to handle a error? As your know, error can be happen in every system and I think this is good if we have a way to communicates error.

I can see one of this way to be best to use.

• Use HTTP status codes as 4xx,5xx.
• Use attribute in the XML document.

<application-list errornr="3" errormsg="server error">

• Use a error XML document.

<error nr="3">Server error</error>
