Hi,

I have two questions related to usage of AND & OR:
1. I found this statement in the Simple's language documentation: 
https://camel.apache.org/components/latest/languages/simple-language.html#_using_and_or
'Notice: Currently && or || can only be used once in a simple language 
expression. This might change in the future.
So you cannot do:
simple("${in.header.title} contains 'Camel' && ${in.header.type'} == 'gold' && 
${in.header.number} range 100..200")'

However I found a unit test that suggest otherwise: SimpleOperatorTest.java 
(methods testThreeAnd, testThreeOr, etc).
Can you please clarify which one is correct? I found some source code which 
uses multiple operators and seem to work fine but I want to be aware of the 
possible consequences, now or in the near future.

2. Also, can you please state if there is any performance penalty in using the 
HTML equivalent code in XML: && instead of && and the || 
Instead of ||?

Thank you
