Only if the OP is serving XHTML as XHTML, which is rare on the web. If
the markup is being served as HTML (which covers the vast majority of
web pages) then what the OP posted is valid markup.

The selectedIndex value of the select element will be -1:

There is no requirement for an option to be selected by default:

therefore you should not expect that one will be. It is prudent to
include the selected attribute for the option that should be selected
by default, even if it's the first one, as suggested by the HTML
specification:
| 17.6.1 Pre-selected options
|
| Zero or more choices may be pre-selected for the user.
| [...]
| Since user agent behavior differs, authors should ensure that each
| menu includes a default pre-selected OPTION.
