RE: [xml] Adding an entity in a textnode

["Labib Iskander, Marcus" <ml cm4all com>]

Hi,
the problem (like daniel wrote before) is, that you would have to add an
entity reference child to the parent element to insert an entity reference.
if you insert a text child with content "afdhgadf&sfdjh;sfgjs" this text
node will contain exactly this character sequence and nothing else! the xml
serialization of this would look like this "afdhgadf&sfdjh;sfgjs"
(asuming the text node is contained in a wellformed document, otherwise no
meaningful serialization exists). Which differs from your sequence in that
the ampersand has been escaped.

Cheers,
  Marcus
