Thank you for your comment:


This is a complicated question and I will try and give you a detailed
reply.  First I will argue that conflicts will not happen.

Then I will spell out what happens if they do.


Derived types are contained in a Schema.  The constructor for the
derived type will be referred to by the prefix for the

schema and the local name of the derived type e.g. mySchema:hatsize.  As
we decided today, functions defined in

the main module will be prefixed with local: and if defined in a module
by the prefix for the module.  So, unless the

user makes an error, it is very unlikely that a Schema and a module will
have the same prefix.


But what if the user does make an error and dynamically binds prefixes
to URIs and creates a my:hatsize constructor

and a my:hatsize function.  I do not know if this will be caught by
static type checking.  I doubt it.  Dynamically, when the

Query encounters my:hatsize, the prefix my: will be bound to some URI
and this will tell it what to execute.


If someone has a better story on how such an error can be caught I would
like to hear it.


All the best, Ashok

Functions and Operators, Section 1.6, 5.2 

Can I have a function of the same name as a derived simple type in the
same namespace? e.g. a hatsize() function? 

What are the override semantics if any?
