Didn't we have this discussion already when I prepared the release of CSL 1.0.1? >From http://en.wikipedia.org/wiki/Backward_compatibility: "If products designed for the new standard can receive, read, view or play older standards or formats, then the product is said to be backward-compatible". So for us, I would define backward-compatibility as the ability of CSL processors written for one specific version (e.g. "1.0.1") to process CSL styles written in an earlier CSL version (e.g. "1.0"). If this proposal is accepted, there would be two ways to encode conditions in CSL styles: the "old" way, where all conditions and the "match" attribute are loaded on cs:if's and cs:else-if's, and the "new" way, where we use the XML structure from the current proposal. Styles would be able to mix & match at the level of individual cs:if's and cs:else-if's (e.g., using the "old" structure for one cs:if, and the "new" structure for the following cs:else-if). Since we keep the "old" structure around, CSL 1.0.1 styles will keep working. Hence the change would be backward-compatible, hence the change would qualify for a 1.0.2 release.
