I am using the following doctype

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
When I validate my page this link for a map to mapquest does not validate, all the ampersands return an error. Not sure how to fix this.


Here is the message from the validator:

Line 52, Column 59: character "&amp;" is the first character of a delimiter but occurred as data.
This message may appear in several cases:

You tried to include the "<" character in your page: you should escape it as "&lt;"
You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
Another possibility is that you forgot to close quotes in a previous tag.

Thanks a lot
