XSD syntax for declaring an element that cannot have a child elementor other content

[Olumide]

Would this be the proper method of declaring an XML element Foo that
cannot have a child element or other content?

<xs:element name="Image" type="xs:string" fixed="" nillable="true" />

The valid uses of this element in an XML document would be:

<Foo></Foo>
<Foo />

Anything else would be invalid, e.g.:

<Foo>stuff</Foo>

Thanks,

PS:
Its just occurred to me that

<Foo>
</Foo>

might be invalid also because of the newline character and other
whitespace characters that appear between the <Foo> and </Foo>

Well if you put 'nillable="true"' on the element then valid markup also is
<Foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:nil="true"/>
