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>.
