Umbraco - XSLT - List Sub Pages from a Specific Node, by Node Id

The following Umbraco XSLT list all sub pages from a specific Node using node ID.  The important bit is Highlighted.  

1)  umbraco.library:GetXmlNodeById(1062) <-- list all sub pages of nodeId 62.

2) You could replace this line above with something like this: umbraco.library:GetXmlNodeById($currentPage/chooseSubPagesToList)

and in your DocType, there would be a contentPicker called 'chooseSubPagesToList.
