The closest Requirement to what you are looking for is:

"The XML Query Language MUST be declarative. Notably, it MUST not
enforce a particular evaluation strategy."

This requirement attempts to ensure that the XQuery specification does
not mandate the use of "indices" to achieve "performance" or "speeed"
(sic).
