Entry Terms
Encoding entry terms.
All entries begin with an entry term. We use <label> to
            identify all entry terms
We add to <label> one
            @type with an additional @subtype when needed:
@type="entry"is required for the main entry term;@subtype="homonym"is optional and used for subentry terms with the same name as the main entry (r2).
Entry terms can be quite complex, including alternate spellings (separated by
            "or"), and/or alternate terms. We include all of these within the
            <label> tag, if possible. One exception is the use in
            biographical entries of life-span dates, which we define as supplemental to the entry
            term, rather than formally part of it.
    <label type="entry">DIANA’S <hi rend="smallcaps">Bank</hi>, or 
        <hi rend="smallcaps">Diana’s Shoal</hi></label>  In some editions, the formal entry term ignores the alphabetical order of the
            entries. For example, biographical entries for well-known figures may use first-name
            last-name in their title, while alphabetizing the entry under the last name. In these
            cases, we use the <choice> tag to include both a normalized and
            the original text.
    <label type="entry">
        <choice>
            <orig>NATHANIEL HAWTHORNE</orig>
            <reg>HAWTHORNE, NATHANIEL</reg>
        </choice>
    </label>
