says:

"Creating your own property types and properties is easy; just define a 
tag class for your new property. The property tag class will need to 
define num with a unique integer ID, and kind which should be either 
edge_property_tag, vertex_property_tag, or graph_property_tag."

But the sample tag class below don't define num.

Has this become obsolete?

The book (on page 52) only mentions an enum, where the value (without 
_t) is set to "a unique #", then BOOST_INSTALL_PROPERTY is called, the 
example on the above page doesn't state a value here as well.
