What is the differences between the following types:

1) “xs:integer”, "xs:int"
2) “xs:nonPositiveInteger”, "xs:negativeInteger"
3) “xs:normalizedString”, "xs:string"
4) “xs:decimal”, "xs:float"
5) “xs:gYearMonth”, "xs:Year"
6) “xs:gMonthYear”, "xs:Month"
7) “xs:hexBinary”, "xs:base64Binary"

Thanks in advance!
