While we're being pedantic ;-) there is no phrase "validity error" in the
document, but we all know what you mean.

The definition for "error" is defined as:
[Definition: A violation of the rules of this specification; results are
undefined. Conforming software may detect and report an error and may
recover from it.]

So, a processor may report the error, and may recover from it.  But the
results are undefined.

Our XML Validator reports non-deterministic content models as errors for
good reason.  We believe that our users want a validator to be as strict and
as accurate as possible ~ thereby maximising the chance that their xml will
be readable by any processor on any platform.
