I think it depends on the query language binding.

For xslt this would be true because the XPath 1.0 data model [1] does
not have a notion of a base URI.

The query language binding for XSLT2 in Annex H on the other hand
defines the data model to be the data model of XDM constructed from an
infoset or a PSVI.

The XDM used in XSLT2 is "XQuery 1.0 and XPath 2.0 Data Model (XDM)
(Second Edition)" [2] and it defines base URI as a required infoset
property.

To rephrase my question: What is supposed to happen with the base URI
infoset property of the included external definition?

Best,
