Attribute “xmlns:v” not allowed here.
End tag “li” seen, but there were open elements.
Unclosed element “div”.
Bad value “” for attribute “datetime” on element “time”: The literal did not satisfy the time-datetime format.
Bad value “” for attribute “src” on element “iframe”: Must be non-empty.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.

Warnings:
The “type” attribute is unnecessary for JavaScript resources.

Attribute with the local name “xmlns:v” is not serializable as XML 1.0.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in Greek but the “html” start tag has “lang="en"”. Consider using “lang="el"” (or variant) instead.
