question about assignment expression

[mennen]

in the 9.2.2 assignment expression section of the documentation http://docs.jboss.com/jbpm/v3/userguide/taskmanagement.html

first-term ::= previous |
swimlane(swimlane-name) |
variable(variable-name) |
user(user-name) |
group(group-name)

what does variable refer to? I mean, the variable could be anything (and not a role or a user or a group) as in the Websale example: item, quantity,address..

And what does the following expression mean?

< assignment expression='previous --> group(hierarchy) --> member(boss)' />

What does assignment 'previous' mean?
and what does the whole expression mean?

Thanks in advance

never mind my question about previous.. i thought the section about assignment expressions ended before i saw the 9.9.2.1. First terms section. :)

But about the variable(variable-name), can anyone give me an example of how it can be used? I'm having a hard time picturing how it can be used.. Excuse my primitive questions, i'm a newbie to jbpm :-)

Thanks
