XML jargon: declaration vs. definition

Hi,



        Consider the following XML element:

<!ELEMENT value (#PCDATA)>
<!ATTLIST value year CDATA #IMPLIED>

        Is this a declaration or a definition ? In Java/C++ there is a clear
distinction between declaration and definition. How about XML ?
	I am apologizing for asking such a simple (stupid?!) question but I need to
clarify the terminology.


Thanks,
Razvan
