The structure decoder supports analysing Zip files, as documented in the PKWARE APPNOTE.

It has support for the most common descriptor headers, notably including Zip64 Extra Fields and the Zip64 End of Central Directory.

It uses the Javascript structure definition syntax instead of the more basic XML structure definition format, as already the current features
of the decoder are hardly doable with the XML format. Future additions (see Roadmap) will make this even more evident.
