XML schemas question

From: Jonathan Rochkind <rochkind_at_nyob> Date: Mon, 27 Jul 2009 11:35:09 -0400 To: CODE4LIB_at_LISTSERV.ND.EDU

Anyone familiar with XML schemas (.xsd)?

Can you help me figure something out. Is there something in the schema 
that specifies what elements can serve as the 'root node'... or is any 
element described in the schema avaialable for use as a 'root node', and 
it'll still validate?

Thanks for any tips.

Jonathan
