+Instead of converting your tabular data into a full XML document you can now import it into an already existing `DOMDocument` object.
+Do to so you need to specify which document the data should be imported into using the  `XMLConverter::import` method.
+
+This method takes two arguments:
 
 - the tabular data as defined for the `XMLConverter::convert` method;
 - a `DOMDocument` object to import the data into.
 
- Of note the resulting DOMElement is attached to the given DOMDocument object but still need to be made visible by using a DOM insertion method like `appendChild` or `insertBefore`.
+ Of note the resulting `DOMElement` is attached to the given `DOMDocument` object but not yet included in the document tree.
+ To include it, you still need to call a DOM insertion method like `appendChild` or `insertBefore` with a node that *is* currently in the document tree.
