Do I need to sort the xs:pattern regex alternatives longest-to-shortest?

[Roger L Costello]

Hi Folks,

Recall that when using dfdl:lengthPattern you must specify its regex 
alternatives longest-to-shortest. For example, if you specify this:

dfdl:lengthPattern="abc|abcd"

then you will get a "left over data" error message.

So you must sort the alternatives in longest-to-shortest order. That is a 
hassle.

The "-V limited" option changes things. It enables me to abandon 
dfdl:lengthPattern and instead use the XSD pattern facet:

<simpleType>
    <restriction base="string">
        <pattern value="abc|abcd"/>
    </restriction>
</simpleType>

Question: Do I need to sort the pattern facet alternatives in 
longest-to-shortest order? I am hoping the answer is "no".
