XML DTD Validate. Difference in Eclipse and other editors

Question

I have XML with inline DTD

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE why [
<!ELEMENT why (animal,weight,age) >
]>  
<why>
 <animal>giraffe</animal>
 <weight>1192</weight>
 <age>26</age>
</why>

Eclipse completes validation with no errors or warnings. But other editors find errors of course. I'm agree with other editors))

Why does Eclipse work this way? Autocomplete? I wonder.

Thanks.
