This line from the Doc CD URL you referenced is certainly a typo:
"route-map default-map 10 permit"
Proof:
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#route-map default-map 10 permit
^
% Invalid input detected at '^' marker.
R1(config)#route-map default-map permit 10
R1(config-route-map)#
I was NOT commenting on the wildcard mask issue.

I am sorry that I forgot to post the URL link. Here is the link:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/
fiprrp_r/bgp_r/1rfbgp1.htm#1158721
However, I don't think it is a typo.
