         It is a serialization error [err:SEPM0016] if a parameter value is invalid for the given parameter. 
         Wrong serialization parameter value for doctype-public.

This test uses assert-serialization-error to test for SEPM0016.  Here is the definition of assert-serialization-error:
    
  "Asserts that the query can be executed without error, but serializing the result
  produces a serialization error.
  The result of the query must be serialized using the serialization
  options specified within the query (if any)."

I think in this case, the test should also allow the error to be thrown during expression processing. From XQuery 3.0, 2.4.4:

  "A processor that is not performing serialization may report errors if any 
  serialization parameters are incorrect, or may ignore such parameters."

So I would like to add an alternate result:

  <error code="SEPM0016"/>

And I would like to make the same type of fix to the following tests as well:

  Serialization-010
  Serialization-011
  Serialization-012
  Serialization-015
  Serialization-017
  Serialization-018
  Serialization-019
  Serialization-020
  Serialization-024
  Serialization-025
