* Constructor
* The Constructor can take a Pear::DB "data source name" (eg.

" If you provide nothing as $dsn, you only can later add stuff with
* a pear::db-resultset or as an array. providing sql-strings will
* not work.
* the $root param is used, if you want to provide another name for your
* root-tag than "root". if you give an empty string (""), there will be no
* root element created here, but only when you add a resultset/array/sql-string.
* And the first tag of this result is used as the root tag.
