Need Some clarification on the RSS 2.0 Specifications

Hi Everyone,

This is my first post in this Forum.

We are developing one RSS client. To validate the XML i need some 
clarification on the RSS 2.0 specification.

1. Can one feed have more than 1 item with the same title? When i 
tried some feed creation tools, some tools did not allow this and some 
did. Can we have some ref. for this?

2. Will PubDate of Channel be updated only when PubDate of an item 
gets updated? Can i use Channel PubDate as a check point validate if 
my XML is changed or not?

I need these info very urgently. 

Your suggestions and answers are very much appreciated.

Thanks
Gandhi
