Root element and schema declaration
Use the root element article for a journal article.
Capture article XML as JATS unless instructed otherwise by OUP.
When capturing an article as JATS, include a DOCTYPE declaration as
shown in the example. The example additionally shows the root element with common namespace declarations.
Give the root element a xml:lang attribute with a single value, lower-case code from the IANA language subtag type list.
Journal article XML must be valid against the JATS 1.3 DTD.
