Question about Extension

[Himal Chuli]

hi guys,
i've the following;
<xs:element name="shoesize">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:integer">
<xs:attribute name="country" type="xs:string" />
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
what's implication of using extension in the above? could someone please explain it?
appreciate.

It means that we are extending a simpleType to have an attribute. If you extend a complexType, you should have a complexContent rather.

we are extending an integer and again defining it as being string. it's kinda confusing to me..so what type of value the attribute's gonna hold now?
could you please explain it?

Integer is the element(shoesize) content type and string is the attribute(country) content type.
Eg: <shoesize country="USA">8</shoesize>
