Hello. I'm developing an XPath host language for querying XML fragments from a repository [http://www.ietf.org/internet-drafts/draft-godoy-webdav-xmlsearch-00.txt] . Since there may be several XML fragments within the search scope, the proposed approach would have implicated a terrible evaluation cost if arbitrary complex queries had been allowed. So I'm trying to distinguish a subset of "basic" XPath features (which would be REQUIRED) from other features that would be OPTIONAL (the latter may be supported or not, as necessary for each particular use-case). As a consequence, features from the "basic" subset are intended to suffice for most use-cases, and their evaluation may rely on a relational database for optimized processing. I would appreciate your feedback about this proposal, as well as any correction about XPath-related issues . Regards, Javier Godoy
