Should the constants be defined where they are used?

The expression types in the Expr interface,
axis specifier types in the AxisSpecifier interface,
node test types in the NodeTest interface,

This would be similar to node types in Node, filter types in NodeFilter.

A benefit from this would be helping to avoiding circular imports.

xml.xpath -> (the parser) -> ExprFactory -> (constants from xml.xpath)
Sure imports could be done in the functions, but top level imports offer
some speed improvements.  Slight, but every little bit helps.
