The issue does appear to have been a missing exclude-result-prefixes. My
initial check was bad (I must be getting old).

Using this XPath search across all the XSLT modules I found modules that
declared the namespace but did not omit the prefix:

'df'))][namespace-uri-for-prefix('df', .)]

Adding the prefix to @exclude-result-prefixes corrected the issue.
