EL usage with and operator throws errors

[infinity2heaven]

What is wrong with this EL in facelets

rendered="#{foo.persistent && foo.isInactive}"

I get the following error:-

The entity name must immediately follow the '&' in the entity reference

Or operator works but not an && operator

Use and instead, it works well. No idea why the regular operator does not work though...

That was simple.

I realized the reason for this was the valid xhtml compliance(facelets) and anything under EL would still be valid xhtml.
