In some cases it is necessary to normalise punctuation in the course of transcribing a text. This may be because the punctuation is used incorrectly in a source text, or is omitted altogether when it should not be.
We would expect to be able to use <choice> as a child of <pc> in the same way as <choice> is used as a child of <w> for encoding diplomatic and normalised word forms (i.e., with <orig> and <reg>). However, the current content model of <pc> does not allow <choice> to be used at all.
The attached example demonstrates what we believe should be permitted.
