shortForm method in Xhtml

Hi there,

In scala.xml.Xhtml, shortForm has been defined as follows[1],

def shortForm =
minimizeTags &&
(x.child == null || x.child.length == 0) &&
!(List("div", "script", "textarea") contains x.label)

IMHO, there must be discussions, but the following definition may be better,
according to XHTML-1.0-strict DTD specification[2],

private val emptyElements = List("base", "meta", "link", "hr",
"br", "param", "img", "area", "input", "col")

def shortForm =
minimizeTags &&
(x.child == null || x.child.length == 0) &&
(emptyElements contains x.label)

emptyElements may be too long and you may want to delete some of tags from it.
