It is not intended to replace the process by which new resource records are defined and implemented. Format of TXT record To store new types of information, the TXT record uses a structured format in its TXT-DATA field. The format consists of the attribute name followed by the value of the attribute. The attribute name is considered case-insensitive. All subsequent characters are part of the value.
Examples indicates a space character.
The attributes can be accessed by the standard resolver library, but it is recommended that a library routine designed specially for this attribute format be used. This routine would remove all quoting characters before returning the information to the caller. A more complex routine could return attributes with multiple values, or several different attributes. To permit ease of interoperability and to reduce the chance of naming conflicts, a registration process for well known attribute names might be established. This paper does not address attribute name registration.
