As you may have noticed, VTD-XML is not
object-oriented in that sense, and thus elements and
attributes are not really bundled together. They are
related, and relationship can be found... but there is
no object-level containment: so there is no concept of
"getting attributes out of an element", just finding
attributes that follow start element/start tag.
Another way to think about that is to note that
attributes are tokens same way as tags themselves are,
ie. granularity is higher than with other toolkits.

Also, as a consequence, looking at other APIs will not
give much insight into knowing how to get attribute
names and values from VTD-XML: the API is quite
distinct due to impl wanting to avoid object
allocation cost at any cost.

I don't have javadocs at hand, but it is not all that
hard to figure it out from the samples. And I'm sure
Jimmy can give a complete example of how to traverse
over attribute names, if and when you do need to know
them all (most of the time you don't -- you know what
to look for).
