About timeDuration format

Hi,

According to XML Schema Part 2 3.2.6, timeDuration's format is
PnYnMnDTnHnMnS.
This is the basic format of time duration. Does timeDuration allow other
alternative formats,
such as
    CCYYMMDDThhmmss/CCYYMMDDThhmmss
    CCYYMMDDThhmmss/PnYnMnDTnHnMnS
    PnYnMnDTnHnMnS/CCYYMMDDThhmmss
    CCYY-MM-DDThh:mm:ss/CCYY-MM-DDThh:mm:ss
    CCYY-MM-DDThh:mm:ss/PnYnMnDTnHnMnS
    PnYnMnDTnHnMnS/CCYY-MM-DDThh:mm:ss

Thanks in advance!
Jing
