Rss 2.0 namespaces and news aggregators

I am developing a newsfeed and would like to define my own namespaces.
Do you know if news aggregators in general recognise extended
namespaces? 

I am having problems understanding how to use namespaces correctly and
don't understand how to declare them. I have been doing lots of
reading, but not actually getting any further. Here is a snip of my
rss feed, can I use namespaces like this?

I know this may seem oblivious to many of you, but for a newbie it can
be quite confusing.
