Hi,
there are some arguments in the pdf, which aren't any problem anymore.
There are algorithms, which copy information from a closed way to a
specific node of this closed way (eg. in mkgmap).
The advantage of this is, that the router can select the entrance-node,
which is best for his users. Eg. a wheelchair-router could use the
entrance-node for wheelchairs. A delivery-router could copy the
information to the delivery-entrace etc. This is more flexible as having
all address-information at the main entrance.
