To check this PR, create XML file like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE article [
  <!ENTITY nbsp "entity-value">

]>           
<article>
	&nbsp;
</article>

It should not have error (this is the fix of the PR)

Declare an <!ELEMENT like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE article [
  <!ENTITY nbsp "entity-value">
  <!ELEMENT element-name (#PCDATA)>
]>           
<article>
	&nbsp;
</article>

It should have error.

Change element-name to article to fix error:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE article [
  <!ENTITY nbsp "entity-value">
  <!ELEMENT article (#PCDATA)>
]>           
<article>
	&nbsp;
</article>

It works but the validation error range is off

Indeed I discovered this problem yesterday, I created an issue yesterday #518 and @xorye should work on it.

@fbricon I merged this PR since test passed and your test is OK. I need this PR to rebase my work with XSD 1.1. For error range please see #518
