Just state in the portal_types that portal_type A is based category 
"foocat". (supposing that foocat is an existing base category in 
portal_categories)

You will then get an accessor created for you
	getFoocatValue()
	setFoocatValue()

You can set a relation between object a and object b by stating
	a.setFoocatValue(b)

Then retrieve the relation by
	a.getFoocatValue()
