That error message is correct. The HTML element `ul` is not allowed to have
a role=3Dnavigation attribute.

The normative (authoritative) specification that defines which particular
role values are allowed on particular elements is the current HTML spec:

  https://www.w3.org/TR/html/dom.html#sec-implicit-aria-semantics

If you look at the row for the `ul` element in the table at the URL above,
you=E2=80=99ll see it says, =E2=80=9CIf specified, role must be one of the =
following:
directory, group, list, listbox, menu, menubar, radiogroup, tablist,
toolbar, tree or presentation.=E2=80=9D

The document at http://www.w3.org/TR/2007/WD-xhtml-role-20071004/ is not
normative/authoritative with regard to the rules for role values in HTML
documents, and it doesn=E2=80=99t claim to be that; in fact the latest vers=
ion of
that document, which is as https://www.w3.org/TR/xhtml-role/ indicates that
document is a Note, which means it has no normative/authoritative status
with regard to anything (instead it=E2=80=99s purely informative).

So while the fact that document has an invalid example is suboptimal, you
also need to understand that many older W3C documents may include invalid
examples; for example, the HTML4 spec has examples that aren=E2=80=99t valid
currently, according to the current rules in the HTML5 spec.
