problem of the "&" character in validation xml

[Romu]

hey

I  list all the characaters accepted in a <html:text > balise .

the current list which works is :

<constant>
           <constant-name>enseigneCommerciale</constant-name>
           <constant-value>^[A-Z0-9,/"';%?!.()\-\s]*$</constant-value>
</constant>

the problem is when i want to add the "&" character .

it says the entity name should be followed by the enity reference .

think it's xml rules .
anyone has tried it yet , i mean to define entity in the validation.xmlfile ?

thanks .
