No, there is nothing to prevent using imports in instance files, and
some in the WebOnt WG (particularly me) believe it is necessary. In my
DAML+OIL instance files, I've always had something like:

<rdf:RDF
  xmlns:rdf = "http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns = "http://www.daml.org/2001/03/daml+oil#"
  xmlns:daml = "http://www.daml.org/2001/03/daml+oil#"
  xmlns:cs = "http://www.cs.umd.edu/projects/plus/DAML/onts/cs1.0.daml#"
>

<rdf:Description about="">
  <imports
resource="http://www.cs.umd.edu/projects/plus/DAML/onts/cs1.0.daml" />
</rdf:Description>

<!-- RDF statements go here -->

</rdf:RDF>

For examples, see http://www.cs.umd.edu/projects/plus/DAML/#content
