changes for fix to bug #2999 (only one attribute of an element is returned in resultset doc)
-added merging for large TEXT nodes when they have been broken up.
-allow multiple attributes to be returned in the resultset doc (uses newly-available field type to determine text vs attribute node).

add retrieval of field type for each node (TEXT, ATTRIBUTE, etc).
this is to support a fix for bug#2999
