Ignore format errors if value is empty

[rudasn]

Just a thought if format errors should be suppressed if the value is empty.

For example

{
  "type": "string",
  "format": "email"
}

should not return an error if the document has an empty string.

I don't think so, since an empty string is NOT a valid email.

in any case, you should take this question up with the mantainers of the json-schema specification, jjv will comply to whatever the schema dictates (i.e. I do not make up the rules for validation, I only implement them).
