You haven't done anything wrong; it's just that not all error messages are
as informative. If the automata-based content model was violated for a
complex type, you'd see the sort of detail shown in the user manual: those
errors tend to be complex and need that level of detail to be understood.
For a facet violation the current message is only what you see. Without
seeing the schema I can't interpret it other than it appears there's a
local simpleType used as a nested element (so it has no XML name as a type)
that requires something longer than an empty string. (The message is "by
value %s", which could be improved so the absence of a value is more clear.)
SimpleFacetValueError is not an UnrecognizedContentError. You can see the
exception hierarchy at:
http://pyxb.sourceforge.net/userref_validating.html#runtime-exception-hierarchy
The API is at: http://pyxb.sourceforge.net/api/index.html
>From there you can go into pyxb.exceptions_ and see that
SimpleFacetValueError has properties for the type, value, and the facet
that was violated. You should be able to print e.location to see the
line/column in the input where the problem was identified.
You can also print e.type._location() to see where in the schema the
anonymous type appears, or delve into e.facet to find what its minimum
length is. You can also look at the generated bindings; the definition for
STD_ANON_12 should also tell you where in the schema the definition
occurred and the minimum length for an acceptable value.
also, am i right in thinkng that there is no way to obtain

Yes. That is not a function that PyXB supports.
