[Wtp-wst-dev] Attribute getSpecified() method.

[David Carver <d_a_carver@xxxxxxxxx>]

I've been going through the W3C DOM Test Suite, and running the DOM 
Level 1 XML core compliance tests against the WTP DOM implementation.   
Several minor problems, I have been able to fix, but there is one that 
is driving me batty, and it has to do with the AttrImpl#getSpecified() 
method in org.eclipse.wst.xml.core.internal.document.

The getSpecified() method is supposed to return the state of the 
attribute.  Whether it's value has been changed or not.   Currently this 
is done by checking to see if the ITextRegion valueRegion is not 
Null...if it is, it returns false if it isn't it doesn't.   
Unfortunately, when running through the DOM doesn't appear to be 
accurate half the time.

When an attribute is removed, the valueRegion should also be removed.   
If the attribute's value is set, the valueRegion should be updated as 
well.   My question is, when and where is the setValueRegion() method 
called.   As it isn't called within the AttrImpl, so I'm assuming this 
is something that was called from the StructuredDocument.    If 
so...then we have a timing issue going on between when this value is 
updated and when the DOM is being read for this value.

Any ideas or thoughts would be appreciated it, this little switch is 
driving me up a wall.
