Keep adding features to solve the kinds of XML transformation problems I keep encountering at an integration level.
Schema handling improvements. Not all the support for schema semantics is catered for by xmlfy which is a shame considering the potential of it being able to support an enormous number of configurations.
It is the intention that xmlfy remains a strictly lightweight and portable tool for free use in shells and scripts.
It would be cool to see xmlfy adopted into the common distributions of Un*x.
