What is the meaning of ":0.0.0" within "inject bean="profile-classloader:0.0.0""

What is the meaning of ":0.0.0" within "inject bean="profile-classloader:0.0.0"" ??

<classloader><inject bean="profile-classloader:0.0.0" /></classloader>

and

    <classloader name="profile-classloader" xmlns="urn:jboss:classloader:1.0" export-all="NON_EMPTY" import-all="true">
        <root>${jboss.lib.url}jboss-profileservice-spi.jar</root>
    </classloader>

http://community.jboss.org/wiki/ProfileServiceoverviewin5x

I found this from the page above, I post this question here because Google cannot search for the ":0.0.0". so sad....

It's a new way of how JBoss defining classloading starting version 5. First section is using(injecting) a classloader object you defined in the second section. The confusing part is that the injected bean name magically use this ":0.0.0" suffix, which is magically added when you define a classloader object. You can explicitly change the version value when you define it, but you can't get rid off it when injecting it!

I don't think I ever get a clear answer as why this confusing version string is used, rather than just letting user use a unique bean name. Not very intuivative. See http://community.jboss.org/message/8690
