Hello.
validator.w3.org say me this code not is valid becouse ELEMENT BODY don't reknow my TAG <planet>:
just I add and declarate this TAG in the DOCTYPE, but previuslly the element BODY is declarated and not include my elements (tags) as <planet>, <star>, <ovni>, etc...
Some idea about how I can eXtend my tags to this document using the DTD from W3C ?
I believe I need rewrite the ELEMENT BODY, but I am no't sure.
Thanks!
