4970	XHTML Compliance :   should be  	andrew_	andrew_	"I've found an issue
with the dialog and XHTML compliance. ThrushAAX was kind enough to
point out in #jquery-ui that if you don't have the title option set
when working with a page properly served up as application/xhtml+xml
that the dialog will cause an error. The exact error within Firefox is
as follows:

Error: undefined entity
Source File:
Line: 1, Column: 43
Source Code:
<div xmlns=""http://www.w3.org/1999/xhtml"">&nbsp;</

Error: uncaught exception: [Exception... ""Component returned failure
code: 0x80004003 (NS_ERROR_INVALID_POINTER)
[nsIDOMNSHTMLElement.innerHTML]""  nsresult: ""0x80004003
(NS_ERROR_INVALID_POINTER)""  location: ""JS frame ::
http://localhost/res/js/jquery/jquery-1.3.2.min.js :: anonymous ::
line 12""  data: no]

Line 38 in jquery.ui.dialog.js is the immediate offender. The simple
fix is to replace instances of '&nbsp;' in the script to '&#160;'.
&nbsp; is an invalid xml entity, and &#160; is the code replacement,
and is recognized in all browsers
