Encoding considerations: This is an XML document and the encoding considerations are the same as for media type "application/xml" defined in RFC 3023 [83].

Thus a target for any attacker that would like modify a receivers understanding of the security functions, either for a denial of service attack or a session replacement attack. However the format contains no seceret information that may not be shared openly. All security keys are handled using other mechanisms. Source authentication and integrity protection is recommended.
