--- Comment #1 from Josh Spiegel <josh.spiegel@oracle.com> ---
It also needs to clarify what the required type is when the schema type is
method-type.   The required type should not be method-type since this would
require importing and casting.  Here is my suggestion:

"For the union types method-type or json-node-output-method-type, the required
type is a union of xs:string and xs:QName.  If the value is an instance of
xs:string, it is treated as a QName in no namespace with a local name equal to
the value.  "

Then the error behavior would then be defined as described in the following
note:

"If the supplied value is of the wrong type for the particular parameter, for
example if the value of indent is a string rather than a boolean, then as
defined by the ·option parameter conventions·, a type error [err:XPTY0004] is
raised. If the value is of the correct type, but does not satisfy the rules for
that parameter defined in [XSLT and XQuery Serialization 3.1], then a dynamic
error [err:SEPM0016]is raised."

For example, the following queries would not raise an error:

  fn:serialize(<e/>, map { "method" : "xml" })
  fn:serialize(<e/>, map { "method" : QName("", "xml") })
  fn:serialize(<e/>, map { "method" : ser:method-type("xml") })
  fn:serialize(<e/>, map { "method" : xs:untypedAtomic("xml") })
  fn:serialize(<e/>, map { "method" : <e>xml</e> })
  fn:serialize(<e/>, map { "method" : validate type xs:QName { <e>xml</e> }})

The following queries would raise XPTY0004:

  fn:serialize(<e/>, map { "method" : 1 })
  fn:serialize(<e/>, map { "method" : () })
  fn:serialize(<e/>, map { "method" : ("xml","json") })

The following queries would raise SEPM0016:

  fn:serialize(<e/>, map { "method" : "foo" })
  fn:serialize(<e/>, map { "method" : QName("", "foo") })
