Usability: Lack of -b binding support in AS7 leads to confusion

The replacement for -b in AS7, from what I understand, is to edit standalone.xml and, under the public interface section, specify <any-address /> as the binding interface. "<any-address />" doesn't seem like an obvious value for specifying the wildcard interface - I'd think that the standard "0.0.0.0" would lead to less problems. If it's impossible to support 0.0.0.0 specifically, or to add support for -b again, then some additional information on the error message that comes back from when a user attempts the -b argument would be more helpful.
