XOM API for Processing XML with Java

[Laurent Bihanic <laurent.bihanic AT atosorigin.com>]

Hi,

I was looking at the XOM 1.0d8 API and found two things that may be worth 
changing:

- setData vs. getValue: Comment, Text and ProcessingInstruction all require to 
use setData to modify the node data and getValue to retrieve this same value. 
On the other hand, Attribute provides setValue and getValue. I think the API 
would be more intuitive if Comment, Text and ProcessingInstruction used 
setValue instead of setData.

- Likewise, many classes offer protected checkXxx methods (e.g. checkRoot, 
checkRemove, checkTarget, checkData) but Comment and Text only have check(). 
For consistency, it would be nice to rename them checkData (or checkValue), 
even if these classes only have one check method (but Document and Attributes 
are in the same case).
