It refers to:

IIRC, w3c schema allow to specify restrictions on an element's
content.  So with a schame we could syntactically constraint a Year
element with something like "\d+( BC)?" so that we have only valid
years - which I suppose would count as an "attempt to prevent this" in
your statement.  Which we can't do AFAIK with a DTD.
