showDocument and hideDocument in polys branch no longer work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create simple map page and parse KML file with only placemarks (not polygons 
or polylines)
2. Invoke parser.showDocument() or parser.hideDocument()

What is the expected output? What do you see instead?
Expectation is that invocation of showDocument or hideDocument when specifying 
document would invoke marker setVisible method.  Because there is no longer a 
markers array at top level of document object, layers with only simple markers 
do not show or hide

What version of the product are you using? On what operating system?
head of polys branch (rev r62)

Please provide any additional information below.
I believe this change will work:

    if (!!doc.placemarks) {
      for (i = 0; i < doc.placemarks.length; i++) {
        if (!!doc.placemarks[i].marker) doc.placemarks[i].marker.setVisible(true);
      }
    }

You are correct.  Some of the functionality that I was trying to implement must 
have meant that I was not seeing that geoxml3 is working properly.  I did make 
an example:
