You can find these details in the source code of Wsdl2Apex. In particular, you want to look of references to TYPE_INFO_PREFIX.

Generally it will be:

  • XML Element Name
  • Namespace for base type
  • XML Type
  • minOccurs
  • maxOccurs
  • isNillable

Have a look at What are the parameters for the Salesforce WebServiceCallout.invoke method?
