SSI Syntax has changed in Apache 2.3.13+, breaks validator's includes

[ssteinerX]

SEE: http://www.zytrax.com/tech/web/ssi.htm

Note: Apache 2.4 (actually 2.3.13+) has changed the syntax of conditional expressions. The old behavior can be restored using the SSILegacyExprParser directive. Why do they do this stuff? Apache 1.3 used to be like a rock for backward compatibility.

Need to either change the syntax (not backward compatible) or add the SSILegacyExprParser directive.

http://httpd.apache.org/docs/current/mod/mod_include.html#ssilegacyexprparser

I'm not sure what happens if that directive is used on < Apache 2.3.13).
