document that an ECPublicNumbers object has some unexpected properties (#4319)
* document that an ECPublicNumbers object has some unexpected properties
It is not guaranteed to be a valid point on the curve as that is not
checked until you convert it to a PublicKey object.
* different language
* move the text, make it a warning, alter the language
* new language
