Appendix C. Error Summary
This appendix lists all of the errors that may be raised during evaluation of a query, in alphabetical order by name. The XQuery spec does not define any programming API defining how queries are executed from, for example, C# or Java; but there is an expectation that in any such API, you will be able to test these error codes to find out what went wrong. In most cases, you can also expect that the error code will be accompanied with an error message that gives much more detailed information.
Error names, which are in the namespace
http://www.w3.org/2005/xqt-errors, are broken down into three parts:
A two-character prefix indicating the specification that defines the error, listed in Table C-1.
A two-character category that groups the error messages into their functional meaning. In the case of
XQerrors, the categories are
STfor static errors,
DYfor dynamic errors, and
TYfor type errors.
A four-digit number.

apply function was called, but the arity of the function in the first argument was different from the size of the array in the second argument. For example,
apply(upper-case#1, ['a', 'b']), where the arity is 1 and the array has a length of 2.
