SAML2 metadata for a SAML1 IdP

The SAML2 metadata schema requires at least one <SingleSignOnService>
element per IdP role.  Unless I'm mistaken, the Metadata Profile for
SAML V1.x does not specify the content of the <SingleSignOnService>
element for an IdP that supports SAML1 Browser SSO only.  What does
the <SingleSignOnService> element look like in this case?

Thanks,
Tom
