As you can see, the XML contains only one Database but an infinite (well, not that much ;) ) number of Tables with a unique name and in which you can have items that could be compared to rows in MySQL.
The differences are :
In a table, you can have items with different attributes as you can see in table1
Attributes can't have different formats (for now). Everything is a @string@. Of course, you can convert them later.
You can move items from table to table! You could even move them to a precise location into your file!
"SQL" command syntax
Data definition (like Create Database, Drop Database, Create Table, Drop Table )
Data manipulation (like Insert, Delete, Update, Select, Move (experimental, only with XMLDB !) )
