org.eclipse.persistence.internal.oxm.XPathFragment
INTERNAL:
Purpose: Represents a token from an XPath statement.

For example the following XPath statment a/b[2]/text() corresponds to three XPathFragments: "a", "b[2]", and "text()".

Responsibilities:
- Maintain name, namespace, and prefix information.
- Maintain information about the corresponding node type.
- Maintain index information if any. The XPathFragment corresponding to b[2] would have an index value of 2.
