The Monkey Script Compiler can save an xml file with any number of valid licenses (for a particular product password). This Wiki page is a description of the xml structure of that file:

The keylist node contains a keycount subnode which indicates the number of defined licenses, and a number of identically named licensekey subnodes, each of which represents a single valid license data block:
Licensekey nodes contain a license string, and they have a number of empty fields for customer information. Of course when you have an XML parser in place it is very easy to add custom fields, but the standard ones are already included...
