What is PaSS
PaSS is a Web content syndication format based on its sister standard RSS.
PaSS is an acronym for Portable and Simple Syndication. RSS stands for Really Simply Syndication and RDF Site Summary.
PaSS is a dialect of XML and is based on RSS 2.0. All documents containing PaSS must conform to the XML 1.0 specification, as published on the World Wide Web Consortium (W3C) website.
RSS 2.0 does not have the ability to include its elements in other XML formats through a namespace. PaSS allows RSS 2.0 elements to exist as vocabularies in other XML documents. PaSS is not an XML file format.
PaSS is being proposed by DeveloperDude.
More on PaSS
From a conversation between DeveloperDude and KenMacLeod.
PaSS leaves RSS issues to be addressed seperately.
(corollary, RSS issues are not considered issues, by some.)
PaSS is not an API
PaSS proposes an embeddable RSS so that, for example, it can be passed as a SOAP document literal within an API
If an API were to be developed using PaSS,
it would parallel the Atom API
at this point, it would be a SOAP-only API, which is why PaSS is embeddable RSS
logically, it would be "the same", just using a different document literal
