(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “javascript:void(0)l” for attribute “href” on element “a”: missing ; before statement
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad value “/aero symposium/” for attribute “href” on element “a”: Illegal character in path segment: space is not allowed.
End tag “a” violates nesting rules.
End tag “div” seen, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
