ParseTreeNode
A non-leaf node's region will encompass the regions of all of its
children. For example, a the region of a function call node
Crossjoin([Gender], {[Store].[USA]})
stretches from
the first character of the function name to the closing parenthesis.
Region may be null, if the node was created programmatically, not from a piece of source code.

method appropriate to the type of expression.
