SAML 2.0 Multiple md: NameIDFormat tag in service provider metadata

I searched for some SAML 2.0 service provider metadata examples and came across a metadata file with several NameIDFormat tags. Now most of the other examples I've seen have only one, so this snippet indicates that SP will accept NameID in SAML 1.1, as well as in SAML 2.0 formats and can accept temporary and permanent name identifiers in case of SAML 2.0 responses?

<md:NameIDFormat>urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress</md:NameIDFormat>
<md:NameIDFormat>urn:oasis:names:tc:SAML:2.0:nameid-format:transient</md:NameIDFormat>
<md:NameIDFormat>urn:oasis:names:tc:SAML:2.0:nameid-format:persistent</md:NameIDFormat>
<md:NameIDFormat>urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified</md:NameIDFormat>
<md:NameIDFormat>urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName</md:NameIDFormat>
