Create a collator from a parameterized URI

Parameters:

uri - the collation URI as written in the query or stylesheet, after resolving against the base URI where necessary

config - The configuration. Provided in case the collation URI resolver needs it.

Returns:

null if the collation URI is not recognized. If the collation URI is recognized but contains errors, the method returns null after sending a warning to the ErrorListener.
