Add handling for choice/sic/corr

[joewiz]

In order to capture known typos in the published/printed editions of our publications, we should explore the use the TEI <choice> element and related elements (see TEI Guidelines on Simple Editorial Changes), which lets us indicate the original, printed words/phrases and corrected words/phrases.

Aspects of this to be developed include:

• enabling these elements in the FRUS ODD and generated schema files
• developing clear practices and documenting how we will use these elements in the FRUS ODD and generated documentation files
• updating the FRUS TEI PM ODD to properly display the new elements
• adding clear explanations for readers so they know how to interpret this information

Initial work on this will be performed in branches of frus and hsg-shell, and will be discussed with Mandy and Kathy before adopting it.

Typos on the printed page fall into several categories:

1. Searchable terms--proper names of various kinds including names, groups, and ships, as well as place names. Typos will keep users from finding documents that match these search terms.

Britian

Canfederate
Duucan,

Oreta

United Staes
Nicaragua,
Mexiro.

Philadelpaia.

2. High-certainty typos—repeated fragments before and after a line break

de-degree
govern-ernment
beeen
gov-government

3. Medium-certainty typos—one letter missing, transposed letters, incorrect usage of similar letters (especially vowels, echoing common OCR error patterns)

ot
whieh
accouut
accopt
lordshid
liad

4. Low-certainty typos--possible legitimate spelling variation at the time

batallion
embassador
exequator

exequatur
Schulz.
siezed

siezure

Another example via the mailbox today: In https://history.state.gov/historicaldocuments/frus1901/d448, the dateline of the attachment contains a typo: "Kinkiang" should be "Kiukiang." As shown in shown on https://history.state.gov/historicaldocuments/frus1901/pg_509, this typo was in the original:

Mr. Kupfer worked in Kiukiang, Kiangsi province (using today's spelling, Jiujiang, Jiangxi province).

It would be nice to inform readers that we are aware of the typo.
