We are planning to support some of the features in 1.1 eventually,
though it is not clear when, since the specification is still
changing and there is no definite timeline from W3C when it will 
become a recommendation.

Also some of the new features proposed for 1.1 may not be practical
for embedded systems. For example, assertions would require a complete
XPath processor plus the construction of a generic XML sub-tree to
evaluate the expression on. Neither of these two requirements are
realistic for most embedded systems.

Also, it would be helpful for you and others interested in XML Schema
1.1 support to provide a list of 1.1 features that you are planning 
to use in your future schemas and would like to see supported in
XSD/e. This way we can get a better idea about which features the 
users of XSD/e are interested in.
