outside reference uisng choice tag in XML Schema

[Ralph Ching]

hello fellow ranchers,

is it possible to use a reference to the other file using choice tag in XML schema?

for example:

<xs:choice>
<!-- this element has a definition inside the current xsd file -->
<xs:element name="student" type="studentType"/>

<!-- This element is in another xsd file named "Teacher.xsd"-->
<xs:element name="teacher" type="teacherType"/>
</xs:choice>
