Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “content-script-type” for attribute “http-equiv” on element “meta”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Attribute “framespacing” not allowed on element “frameset” at this point.
Attribute “border” not allowed on element “frameset” at this point.
Attribute “frameborder” not allowed on element “frameset” at this point.
Attribute “frameheight” not allowed on element “frameset” at this point.
Attribute “framewidth” not allowed on element “frameset” at this point.
The “frameset” element is obsolete. Use the “iframe” element and CSS instead, or use server-side includes.
The “noframes” element is obsolete. Use the “iframe” element and CSS instead, or use server-side includes.
