Description Michael Kay 2005-08-22 15:01:41 UTC 
In section 3.1.5, XPath contains the statement:

If the expanded QName and number of arguments in a function call do not match
the name and arity of a function signature in the static context, an error is
raised (the host language environment may define this error as either a static
or a dynamic error) [err:XPST0017].

The clause in parentheses is there because XSLT until recently defined this
error as a dynamic error when running in forwards-compatibility mode. Following
a recent decision on issue 1230, this is no longer the case. Therefore, the
clause can now be removed. The paragraph can now be replaced with the version
that is used in the XQuery specification.

The change suggested by Michael Kay was approved by the joint Query and XSLT 
working groups on Aug. 30, 2005, and has been implemented in the XPath document.
