If you want callbacks named after element types, then there is no way
out other than to do some name mangling. There are lots of characters
valid in SGML/XML element type names that are not legal in function/method
names. Characters like "-" and "." are popular ones:-)

The SAX way is to have a generic element handler to which the
element type name is passed as a String. This gets round the
problem but is sooooo much less convenient than the element
specific callback approach.
