Currently, the last sentence of section 1.4 of Overview is:

".. but only some RDF documents wll [sic] be a legal OWL Lite or OWL DL 
document. "

I suggest to add the following:

Because of this, some care has to be taken when a user wants to migrate
an RDF document to OWL. When the expressiveness of OWL DL or OWL Lite is
deemed appropriate, some precautions have to be taken to ensure that the
original RDF document complies with the additional constraints emposed
by OWL DL and OWL Lite. Among others, every URI that is used as a class
name must be explicitly asserted to be of type owl:Class (and
simililarly for properties), every individual must be asserted to belong
to at least one class (even if only owl:Thing), the URI's used for
classes, properties and individuals must be mutually disjoint.  The
details of these and other constraints on OWL DL and OWL Lite are
explained in appendix @@@ of the OWL Reference.
