p. 26 of the 1.00 Assembly Spec describes a mustSupply attribute on a

1.0 Tuscany or any discussion of it on the mailing lists. Has the
attribute gone for good, and has the concept gone as well?
I am assuming that the noDefault attribute (used to be "required") is for
use just within a component type but perhaps that's wrong.

The mustSupply attribute described in the assembly spec is implemented
by the Tuscany assembly model, XML readers and writers.
The SCA XSD says:
<attribute name="noDefault" type="boolean" default="false" use="optional"/>
instead of
<attribute name="mustSupply" type="boolean" default="false" use="optional"/>
IMO this is a bug in the XSD, I'll report the issue to the OASIS
assembly TC.
In the meantime, you can try to specify that mustSupply attribute
anyway. It should work in Tuscany and XMLSchema validation shouldn't
complain about it as the XSD for <property> allows for <anyAttribute
namespace="##any" processContents="lax"/>.
