[Zope] newbie Q.stylesheet 'title'

The 'title' that appears to the right of an object in a folder Does this need to be included in a style sheet for access. I have been messing around with the zope zclasses howto and notice the use of RTC to generate unique "id"'s to add some meaning to this they also use "title" eg. if one created a zope method and gave it a title how does this differ from the title definded in a style sheet. brad
