Phases in SDL Tridion Event Handler 2011
===

Have difficulties in understanding Event phases.

1) Consider the Component Save action. When the content is to be overridden based on the content rule, it can be done so in 'Initiated' phase. In case of content disobeying the content rule, errors can be thrown in 'Initiated' or 'Processed' event phases . 

When 'Initiated' phase itself is sufficient both for content overriding and content rule validation, When will 'Processed' phase be useful? Pls. explain with an example.


2) While saving and closing the component, 'Save' and 'CheckIn' events are triggered. After the 'Processed' phase of Save action, CheckIn action will take place. In case of any errors during 'Initiated'/'Processed' phase of CheckIn action, 'TransactionAborted' phase of Save action will occur.

Above is the only example that I could think of for 'TrasactionAborted'. Can you provide any other example which will help in understanding 'TrasactionAborted' phase?
