Custom DocType
In the documentation it reads
"To create a Visualforcepage with an XHTML 1.0 Strict document type, use thedocTypeattribute on the<apex:page>tag, and specify a value of xhtml-1.0-strict"
However, when I view the source of my Visualforce page it still has
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
We are using 23.0. Am I missing something? I tried a value of "html-5.0" as well with no luck.
