+/**
+ * TParameterMap corresponds to the <parameterMap> element.
+ *
+ * TParameterMap holds one or more parameter child elements that map object
+ * properties to placeholders in a SQL statement.
+ *
+ * A TParameterMap defines an ordered list of values that match up with the
+ * placeholders of a parameterized query statement. While the attributes
+ * specified by the map still need to be in the correct order, each parameter
+ * is named. You can populate the underlying class in any order, and the
+ * TParameterMap ensures each value is passed in the correct order.
+ *
+ * Parameter Maps can be provided as an external element and inline.
+ * The <parameterMap> element accepts two attributes: id (required) and extends (optional).
