Message
Invalid Namespace Specific String: attribute
Explanation
The SSSE requires that this attribute's value to conform to the syntax for Namespace Specific Strings (the NSS portion of a URN) in RFC 2141.
Solution
Consider replacing characters which are not in the allowed list with a
% followed by two hex characters. If the character in question
is not in the range allowed by the ASCII encoding, encode the string as
utf-8 first, and then percent encode any octets not in the <trans>
list.
