Fixing the breaking error specifically looks pretty trivial, and I can submit a patch for that in case it's deemed helpful.
(Although there's likely other things wrong with this document and those bugs I probably cannot fix.)

@Snuffleupagus, feel free to fix whatever you want ;): your help is greatly appreciated.
Anyway, the binding ref make a reference to $record: as far as I understand specs, it's related to data coming from an external source (see chapter Exchanging Data Between an External Application and a Basic XFA Form) so we won't implement anything related to that stuff but if I misunderstood specs please tell me.
And there are few layout issues...

$record allows for windowing a larger dataset, including XML embedded in the xfa data dom. For example, a subset of data can be rendered on to the form at once. The config dom present.common.data.record value stores the location of the repeating record value. I can upload an example if needed.
