In the case of GTFS, it appears that Google had both the incentive (more people using their maps) and the resources to create the initial code and documentation.

The problem with this approach is that its using politics to define technical interfaces, a process which has brought us lots of the funnies failures of eGovernment. Different problems require different solutions, and business accounting and government finance are fairly different domains.

The promise of being able to use common interfaces for this data just never became true, because the complexity of XML (and XBRL) actually makes it less likely that different systems will be speaking the same language. I'm dealing with another example of heterogeneous XML right now, and it's hell to code: https://github.com/pudo/ted-xml/blob/master/forms/contract_award.py.

The format is a zip bundle of CSV files and it's easy enough that virtually any larger municipality on this planet can produce it; I've also seen parsers for it written in hours. Of course you can have validation for it, just like XML schema: taxonomies are tables, too.

Specifically, we had a lot of spelling variations across different cities for revenue and expenditure items. This kind of issue could be detected prior to import by validating the XML against a taxonomy using off-the-shelf tools like Altova XMLSpy.

In the end, releasing government data as XBRL could mean that only solutions from large companies like IBM or SAP would be able to invest the effort necessary to interpret the data.

However, a publicly available machine readable file is better than a publicly available PDF, since it is easier to process. In the world of machine readable files, I see XBRL as better than CSV because XBRL tags allow for more complete self-documentation of the data, especially if it the data is complex.
