Question about grammarLocation

[Yonekura Koji <yonekura@educ.mt.nec.co.jp>]

Isn't specification of a schema location like XML Schema performed in RELAX NG? 

<foo xmlns:rxi="http://relaxng.org/ns/structure/0.9"
     rxi:grammarLocation="http://exsample.com/schema/foo.rng">
</foo>

For example, can't it use as follows? 

[foo.rng]
<grammar xmlns="http://relaxng.org/ns/structure/0.9">
  <element name="foo">
    <ref name="content"/>
  </element>

  <define name="content">
    <zeroOrMore>
      <element>
        <anyName/>
        <ref name="content"/>
      </element>
    </zeroOrMore>
  </define>
</grammar>

[bar.rng]
<element name="bar" xmlns="http://relaxng.org/ns/structure/0.9"/>


<foo xmlns:rxi="http://relaxng.org/ns/structure/0.9"
     rxi:grammarLocation="foo.rng">
  <bar rxi:grammarLocation="bar.rng"/>
</foo>
