more formal definitions

[kvlahromei]

If we want to get good formal definitions (see #7 ) we might also bring some more logic into datastructures, so validation might be easier. This includes esp.:

• attribute.code
• attribute.order
• service.id
• address
• ...

This might also result in discussions (e.g. do we consider IDs always to be strings (e.g. hashes, hex numbers, ...) or just positive integers, ...)?

It doesn't look like this is properly covered in the documentation, but I think everything (other than hashes/arrays) should be a string.

[kvlahromei]

Ok a string. This excludes any special characters that might corrupt any marshelling/serializers or the use within URLs, right? So just an alphanum string?
