The current draft has this in Section 4.6: ------------ Subtags defined in the IANA registry as having a specific private use meaning convey more information that a purely private use tag prefixed by the singleton subtag 'x'. ------------ Strictly speaking, that's not true: a private-use *subtag* conveys *no* information (except by private convention -- which is clearly not assumed in this statement), and so cannot convey more information than anything else. Suggested revision: ------------ Tags created using subtags defined in the IANA registry as having a specific private use meaning can convey more information that a purely private use tag prefixed by the singleton subtag 'x'. ------------ Also, this wording is a bit problematic: ------------ However, in some cases content tagged with private use subtags MAY interact with other systems in a different and possibly unsuitable manner compared to tags that use opaque, privately defined subtags, so the choice of the best approach sometimes depends on the particular domain in question. ------------ Tags that use private-use subtags vs. tags that use opaque, privately-defined subtags? Those sound the same. Suggested revision: ------------ However, in some cases content tagged with private-use subtags MAY interact with other systems in a different and possibly unsuitable manner compared to tags that use opaque, private-use subtag sequences prefixed by 'x', so the choice of the best approach sometimes depends on the particular domain in question. ------------ Peter _______________________________________________ Ltru mailing list Ltru at ietf.org https://www.ietf.org/mailman/listinfo/ltru
