Difference betwee birthdate and birthDate - should we be case-sensitive?

[ewoutkramer]

[16:05:23] Al Amyot: Ewout, I've also noticed that on your server, "birthdate=1945-01-01" returns 1 result and "birthDate=1945-01-01" returns ALL results. I've searched the FHIR spec for references to case sensitivity/capitalization and have not managed to find whether the terms should be case-sensitive or not. Is your server's behaviour correct? If the term should be case-sensitive, should the server return an error when the wrong one is supplied?

From the spec: Servers are not required to enforce case sensitivity on parameter names, though the names are case sensitive (and URLs are generally case-sensitive).

The server doesn't have to return an error for search parameters it doesn't understand. When issue #44 has been resolved, it will be more clear the server didn't take birthDate into account.
