There was a proposal developed by Mary Fernandez which I thought would work quite well. It was developed as joint work by the XSL and XQuery groups. On the XQuery side there were some people who didn't want it at all (too complex for a version 1 feature), and others who felt it didn't go far enough (for example in making exceptions first-class objects), but IIRC the main blocker was that one shouldn't make decisions about try/catch in the absence of a transaction model, because it would inevitably interact with rollback/commit. So XQuery decided to leave it to version 2. XSL WG then considered whether to pick it up independently, and decided not to, partly because at that stage of development there was reluctance to add anything that wasn't explicitly on the requirements list because timescales were already running so late, and partly because we didn't want to be wrong-footed by anything that came out of joint work later.
