What is Collection Name attribute used for?

Hi all,

I taught XFM concept/technology and how to create own project recently and I found out I don't know (and so not able to explain well :-) for what can be used the attribute Collection Name. I know what is filled in GSA when new feature / subfeature / collection is created, but there is no much information about it in help file.

Are there any examples or more detail explanation available?

With regards,

  Jan
