I see (responding to your point about it not being related to ancestor 
elements). But I was trying to find somewhere where the issue was made 
explicit as to how xml:base is not only based on the parent, since there 
are these following lines (and basically only these lines on the topic) 
which only refer to "parent element" and not clearly to an indefinite 
number of levels of inheritance of within the document (and regardless 
of whether xml:base was explicitly present on the parent or not, etc.):

"The base URI of an element is...the base URI of the element's parent 
element within the document or external entity, if one exists..."

"The base URI for a URI reference appearing in an |xml:base| attribute 
is the base URI of the parent element of the element bearing the 
|xml:base| attribute, if one exists within the document entity or 
external entity, otherwise the base URI of the document entity or 
external entity containing the element."

Maybe that is made clear in other referenced specs, but since this seems 
to be such a central point of the spec, I would think clarifying that 
would be helpful.

thank you,
