Hi Paul.

An issue (issue #1[1]) was opened following your email to
www-ws-arch[2] about the meaning of a priori knowledge.

The Web Services Architecture Working Group agreed during its 27 Feb
2003 that a priori knowledge was actually prior knowledge, i.e. the
knowledge that two parties have about each other before interacting
(e.g. the service description), as opposed to what "a priori" hints
at: what knowledge a party has (e.g. understanding of XML).

The email discussions about this appear in the following threads:

  WSA issue 1: what is a priori knowledge?

  A Priori Information (Was Snapshot of Web Services Glossary)

and the minutes of the call where the decision was made:


As a result, AR023.7.1 in the Web Services Architecture
Requirements[3] will be updated to reflect this change.
