There are two different questions here: what characters can appear
in a [base URI] Infoset property, and what characters can appear
in an xml:base attribute value?
The [base URI] property of a document, element, or PI is a URI;
as such, it can only make use of a limited repertoire, a subset
of ASCII characters.
The value of an xml:base attribute is not so limited: it can contain
(almost) arbitrary Unicode, which is %-escaped before being used
to alter the base URI property of the element on which it appears
and the element's children.
