Place each affiliation directly within an <aff> element after all <contrib> elements, but within the <contrib-group>. Each <aff> element should contain a single and complete affiliation

Give the <aff> a unique id of the form "aff{lowercase letter}"
Include a <label> element; the label should contain the superscripted, lowercase letter that matches the letter used in the <xref> in the <contrib> (see Authors or the example below for linking an author to his or her affiliation)
Use <institution> to tag an author's institutional or organizational affiliation
Use <country> with @country set to the appropriate ISO 3166-1 alpha-2 country code
If a city, state/province, or postal code is present in the affiliation, tag using <city>, <state>, <postal-code>. Note that these elements are not required and are not always present in affiliations.
If a valid Ringgold institutional ID is present, place within <institution-id> with attribute @institution-id-type set to "Ringgold"
Do not use @specific-use on <aff>

If the author has an email address, do not include it in <aff>. Instead, include it after the <string-name> element, before the <xref ref-type="aff"> (see Authors).
