### 3.6.19 WHILE - Conditionally loop over a Template Block

Conditionally repeated block. Its arguments are evaluated (see section EXPR - Evaluate and emit an Expression) and as long as the result is non-zero or a string with one or more bytes, then the condition is true and the text from that point until a matched `ENDWHILE` is emitted.

    [+WHILE <full-expression> +]
    emit things that are for the true condition[+

    ENDWHILE +]

`<full-expression>` may be any expression described in the `EXPR` expression function, including the use of apply-codes and value-names. If the expression yields an empty string, it is interpreted as false.
