Error type
Clarification
Error description
The POWDER and POWDER-S Internet Media Type/Macintosh File Type definitions given in Appendices B and C of POWDER: Description Resources both indicate that there are no optional parameters. This is incorrect as the charset parameter may be included exactly as defined for application/xml in RFC3023.
Correction
The POWDER and POWDER-S Internet Media Type/Macintosh File Type definitions are repeated below with the optional charset attribute included. This does not affect conformance.
Normative Correction
None

TAG Finding 3 June 2002 (Revised 4 September 2002)

The Internet Media Type / MIME Type for POWDER is "application/powder+xml".

It is recommended that POWDER files use the file extension of .xml (all lowercase) on all platforms.

It is recommended that POWDER files stored on Macintosh HFS file systems be given a file type of "TEXT".

Type name:
application
Subtype name:
powder+xml
Required parameters:
None
Optional parameters:
"charset": the parameter has identical semantics to the charset parameter of the "application/xml" media type as specified in [RFC3023], section 3.2.
Encoding considerations:
Identical to those of "application/xml" as specified in [RFC3023], section 3.2.
Security considerations:
POWDER is used to make assertions, sometimes socially sensitive, about web resources. Consumers of POWDER should be aware of the source and chain of custody of this data. Security considerations for URIs (Section 7 of RFC 3986 [RFC3986]) and IRIs (Section 8 of RFC 3987 [RFC3987]) apply to the extent that describing resources in POWDER may prompt consumers to retrieve those resources.
Interoperability considerations:
There are no known interoperability issues.
Published specification:
