The variable here is:
private var xmlData:XMLList;
OK, fine, it works, but the compiler generates "warning"
errors for every one of those XML references, saying:
"Data binding eill not be able to detect changes to XMLList
'step 1', need an XML instance."
I get that it means that if there were changes to this
variable in the data grid, the won't get saved to the XML file
(right?). If so, in this case I don't care, I only want to DISPLAY
strings from my XML. No editing will be allowed.
