Choice

Use <choice> to encode alternate versions

The <choice> tag groups a number of alternative encodings for the same point in a text. This element enables the encoder to represent the text in its original form, alongside one or more edited forms. This usage permits software to switch automatically between one view of a text and another, so that (for example) a stylesheet may be set to display either the original text or an editorial change.

The element <choice> should contains at least two other elements, each with one of the alternate forms. We use this to record a misspelling and its correction, and an abbreviation in the original and its expanded form. The codes are as follows:
original alternate description
<sic> <corr> misspelling and its correction
<abbr> <expan> abbreviation and its expanded form
<choice>
    <sic>propably</sic>
    <corr>probably</corr>
</choice>

The example shows the encoding if we want to include corrections for a misspelling.

The order of the two alternates is critical. Always put the tag with the text as written first, followed by the emendation. This allows us to define which choice to output in a stylesheet.
