Contributor Cross References

Contributors with any associated affiliation, footnote or biography information must have that information explicitly linked using an <xref> element.

Each <xref> element must have a @ref-type attribute with the value set depending on what is being linked to. The allowed values are:
Table 1. @ref-typeAllowed Values
Xref Target @ref-type Value
Affiliation aff
Biography bio
Footnote fn

Each <xref> element must have a @rid attribute which contains the identifier for the target of the xref.

If the target of the <xref> has a <label> element then the text of that label must also be included as the text content of the <xref>.

Example

<contrib contrib-type="author">
  <name name-style="western">
    <surname>McGurn</surname>
    <given-names>Arthur R</given-names>
  </name>
  <xref ref-type="aff" rid="bk978-0-7503-3579-9aff1"/>
  <xref ref-type="bio" rid="bk978-0-7503-3579-9bio1"/>
