HTML markup errors and warnings
(Rescan now...)
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 “de_CH” for attribute “lang” on element “html”: The language subtag “de_ch” is not a valid language subtag.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
The “scheme” attribute on the “meta” element is obsolete. Use only one scheme per field, or make the scheme declaration part of the value.
Bad value “reply-to” for attribute “http-equiv” on element “meta”.
Element “link” is missing one or more of the following attributes: “itemprop”, “rel”.
The “rev” attribute on the “link” element is obsolete. Use the “rel” attribute instead, with a term having the opposite meaning.
Bad value “schema.dc” for attribute “rel” on element “link”: The string “schema.dc” is not a registered keyword.
Element “dl” is missing a required instance of child element “dd”.
The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Empty heading.
