XML Schema validation questions

We are using W3C XML Schema definitions to validate our XML 
and it has proven useful within an XML IDE. Did have some questions:

1) Is there any way to employ XML Schema to validate the XSLT stylesheets to
make sure that they are up-to-date with the XML?

2) Is there any recommended development practice for employing XML Schema
validations during development of a system and then turning it off in
production? (This assumes that we are producing all the XML and trust
ourselves in deployment).
