RFR: 8023276: Java SE should include the full DOM API from JAXP

[huizhe wang]

Hi,

Three packages are missing from the DOM API documentation in JAXP:
         org.w3c.dom.views
         org.w3c.dom.ranges
         org.w3c.dom.traversal

We added org.w3c.dom.views in JAXP 1.6 and fixed JDK-8006843. But since 
we were too close to the deadline for JAXP 1.6 MR, we left the other two 
packages for JDK 9.  CCC has been approved for this addition. Please review.

Thanks,
