Actually, for XForms, 'inline' and 'linked' are precisely the two ways
of incorporating schemas:  the xforms:model element can hyperlink
to schema documents using the 'schema' attribute:

  <xf:model schema="http://example.com/foo/foo.xsd ..."> ...

and it can contain inline schema documents:

  <xf:model>
    ...
    <xs:schema targetNamespace="http://example.com/foo/foo.xsd">
    ...
    </xs:schema>
    ...
  </xf:model>

I take these to be what the spec is referring to when it speaks
of schemas (or schema documents) being inline or linked.

Note, however, that XForms processors vary a bit in how fully they
support XSD.
