The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Bad value “http://n.neurology.org/content/by/section/Patient Page” for attribute “href” on element “a”: Illegal character in path segment: space is not allowed.
Bad value “auto” for attribute “height” on element “img”: Expected a digit but saw “a” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “http://www.neurology.org/content/by/section/Patient Page” for attribute “href” on element “a”: Illegal character in path segment: space is not allowed.
Warnings:
Attribute with the local name “xmlns:mml” is not serializable as XML 1.0.
The “banner” role is unnecessary for element “header”.
