I don't want to define any field queries

I admit to not having much experience with XML parsing - or a good overview of all the issues with this module. I just wanted something to parse an XML feed that a client gave me.
... and feeds_xpathparser seemed better than rolling my own parser.
... and since my document is simple (see below), I used the plain 'XML' method, without installing QueryPath.

My document looks roughly like:

<xml>
  <stuff>
    <item>
      <field1>value</field1>
      <field2>value</field2>
      <field3>value</field3>
      ...fields...
      <field30>value</field30>
    </item>
    <item>
       ...fields...
    </item>
    ...items...
  </stuff>
</xml>

...so, one encompassing 'stuff' element. (Since I didn't even know all the fields present, and there were many, I've been fiddling with "defining mapping on import" - but I guess that's besides the point here.)

The point: I just wanted to define one query for the 'Context', as Feeds Xpath Parser names it: "//stuff"
And I don't want to define anything else. No per-field queries. Just have it return all (mapped) fields.

Thing is: for the XML parser, if you leave the per-field queries empty, nothing is returned -- because $this->sources[] isn't populated. (The XPath parser may have different defaults...)

So does it make sense to 'by default' (when queries are empty), return all field content?
(This is equal to running $xml->xpath('//fieldNN'), in your code - so that's how I hacked stuff.)

Or can we not assume such a default for all situations?
Or can we only do that for class FeedsXPathParserXML, not for class FeedsXPathParserHTML?
