I think the answer to that is in principle yes, but in practice no.

In principle you can validate a document by specifying either an element
declaration or a type. Every document validates against the type xs:anyType.
However, many schema processors only support the option to validate against
an element declaration, and in that case, the schema must have an element
declaration whose name matches the outermost element of the instance
document.

You'll have to ask someone who knows Galax.
