On our June telecon we committed to discussing the length of the deprecation of a few silly default attributes on this list. So I'm kicking off the conversation. 1) There are a bunch of attributes which have "unknown" as a default value, which we now plan on deprecating. (See ticket 1456 for a list of them.) Does this need a full 2 year deprecation, or is a shorter term more appropriate given how uncontroversial this is? 2) The class att.msExcerpt provides the @defective attribute, which has a default value of "false", which we'd also like to deprecate, but we're waiting for feedback from the TEI-L and MS-SIG before we do so. If the answer from those venues is "nope, nobody cares", do we do a full 2 year deprecation or not? My personal opinion is that (presuming we get the stylesheets to do the right thing, and presuming the prose, if any, is fixed up to match at the same time) 1 year is *plenty* for (1). (I might even be talked into 6 months.) I don't have a strong opinion on (2).
