If the value can't be set an error should be returned rather than the
input ignored.
I agree with all the comments related to switch statements and ignoring
return values, will address them in next version.

This just looks like a normal operation?
Yes, this can probably go into a TLV control, will fix this in next version.

Again, values should not be ignored on error.

Again, switch statements - I'll never understand why people seem so
intent on writing if trees :(
