HTML markup errors and warnings
(Rescan now...)
Errors:
Malformed byte sequence: “f3”.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Obsolete doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Internal encoding declaration “iso-8859-2” disagrees with the actual encoding of the document (“utf-8”).
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Element “metaname="abstract"” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Malformed byte sequence: “b3”.
Malformed byte sequence: “ea”.
Malformed byte sequence: “b6”.
Malformed byte sequence: “bc”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “metaname="abstract"”.
Warnings:
Element name “metaname="abstract"” cannot be represented as XML 1.0.
