Pardon, what was your new error message suggestion?

It isn't. But the error message is perhaps not quite clear. My suggestion:

end tag for "..." which lacks required content element(s)

> I thing you expect <ul><li>some</li></ul>,

That's more or less what the DTD says. A <ul> element must contain one or
more <li> elements (and nothing else).

There's no point in arguing with a validator, which has just analyzed
whether your document complies with the DTD you have specified.

(Practical hint: When you generate HTML markup dynamically and some list
might be empty, either test for this before emitting the <ul> markup, so
that there will be no <ul> element, or emit an empty <li> element,
<li></li>, which is poor usage but valid.)
