isArray behavior on missing/empty tags

[faljse]

"isArray" is true for References.Reference
"alwaysCreateTextNode" is true

case 1:

  <UAReferenceType>
    <References>
      <Reference></Reference>
    </References>
  </UAReferenceType>

UAReferenceType.['References'] is an array

case 2:

  <UAReferenceType>
  </UAReferenceType>

UAReferenceType.['References'] is now undefined; evals to false

case 3:

  <UAReferenceType>
     <References />
  </UAReferenceType>

UAReferenceType.['References'] now contains an object with ['#text']; evals to true

isarray saves me from a lot of extra checks; still it seems like this could be improved?
