Sean is worried that a nonvalidating processor won't
fetch the DTD & therefore won't apply the default
"STUFF" value of the "text" attribute to the 2nd
<lit> element in his instance, and thus won't
make the required substitution.
I.e., validating and non-validating processors
will produce different results.
First of all, in this scenario, you really should
have an XML declaration with standalone="no" as a
hint that the DTD's going to change the document, so
the example already contains de jure bad practice.
The deeper and de facto bad practice is in having a
production system rely on defaults out of an external
DTD subset at all. Sean gives a good example of why
this is the case. Avoid this bad practice and you're
