The user data. Type: xsd:string |
The version and encoding attributes
are required.
The user data is base64-encoded as described in RFC3548 with the following additional restrictions:
Implementations MUST NOT add line feeds to encoded data.
Implementations MUST pad the end of the encoded data with '=' if required.
Implementations MUST ignore characters in the encoded stream that are not in the encoding alphabet. This differs from RFC3548, but provides more leeway for clients.
Implementation MUST use the encoding alphabet in table 1 of RFC3548 (i.e. A-Za-z0-9+/).
Implementation MUST follow the user data size limit before base64 encoding.
