+
+Exceptions
+==========
+
+This standard specifies expected syntax and semantics for a set of APIs. When
+inputs to an API do not match what is expected, libraries may emit warnings,
+raise exceptions, or misbehave in unexpected ways. In general, it is not
+possible to foresee or specify all the ways in which unexpected or invalid
+inputs are provided. Therefore, this standard does not attempt to specify
+exception or warning types to the extent needed in order to do exception
+handling in a portable manner. In general, it is expected that array library
+implementers follow `the guidance given by the documentation of the Python
+language <https://docs.python.org/3/library/exceptions.html>`__, and either use
+builtin exception or warning types that are appropriate for the
+situation or use custom exceptions or warnings that derive from those builtin
+ones.
+
+In specific cases, it may be useful to provide guidance to array library
+authors regarding what an appropriate exception is. That guidance will be
+phrased as *should* rather than *must* (typically in a *Raises* section),
+because (a) there may be reasons for an implementer to deviate, and (b) more
+often than not, existing array library implementation already differ in their
+choices, and it may not be worth them breaking backward compatibility in order
+to comply with a "must" in this standard.
+
+In other cases, this standard will only specify that an exception should or
+must be raised, but not mention what type of exception that is.
