The DTD of XHTML defines the <body>-tag as <!ELEMENT body %Block;> and %Block is further defined as
<!ENTITY % block "p | %heading; | div | %lists; | %blocktext; | fieldset | table"> <!ENTITY % Block "(%block; | form | %misc;)*">
Watch the * in the definition of %Block: zero or more times! So %Block can be empty, hence <body> can be empty and can be written as <body/>.
Also the official validator at W3C says it is valid XHTML1.0
