Attribute for first element only

[FredsFriend]

Hi i'm not sure of how to specify in a W3C schema that the first element only has a specific attribute.
e.g.

<example>
<component firstOnly="stuff">one</component>
<component>two</component>
<component>three</component>
</example>

Or can this sort of thing only be done with RELAX NG or Schematron?

You can't do this via an XSD -- all "component" tags are treated the same, so specifying the attribute as optional will result in any of them potentially using it.
