It was a question.

As I understand it, the scope of the xml-stylesheet PI is all XML
document types under browser class user agents.  If so, for the
xml-stylesheet PI the range of possible values for "type" might be
expected to go beyond the range for HTML's rel="stylesheet link
elements.

There would be a sanity feature in requiring a match, but not a
security feature.  It strikes me that that possible values of the
xml-stylesheet "type" PI might want to ride with XML document type
definitions and the "application/xml" umbrella now in use at W3 for
"http://www.w3.org/Math/XSL/" is indeed sensible unless some browser
provider sees a need to know the stylesheet type from the
transport header before knowing the root XML namespace.
