xml:base
Base
Provides a base URI for identifiers in the XML-tagged standards document or a part of an XML-tagged standards document. Within this standards document, or a 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://mulberrytech.com/”, a URI inside the document of “scope/rationale.html” would be processed as if it were “https://mulberrytech.com/scope/rationale.html”. Values of @xml:base are inherited from the closest base, 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.
