Provides a base URI for identifiers in the XML document or a part of the XML document. Within this document, or portion of
the document, all URIs are assumed to be built on the "base" provided as the value of this attribute. For example, if a document
has an @xml:base
of "https://jats.nlm.nih.gov/", a URI inside the document of "publishing/rationale.html" would be processed as if it were
"https://jats.nlm.nih.gov/publishing/rationale.html". Values of @xml:base
are inherited; meaning that if there is an @xml:base
on a document and on a part of the document, uses inside the part of the document take the value of the part, not the whole.
