Nick Burch commented on TIKA-2241:
----------------------------------
You only need to specify a mimetype for a parser if you want to bind it to a
type it wouldn't normally handle, or to specify an exclude to have it ignore a
type it otherwise would do
If you create a custom config file which does bind an extra mime type to one
file, then dump that, you should still see it listed just for that parser
> DumpTikaConfigExample generates strange tika-config.xml

> Project: Tika

> With Tika 1.14 I get:
> {code:xml|borderStyle=solid}
> <?xml version="1.0" encoding="UTF-8" standalone="no"?>
> <properties>

> The following problems IMHO:
> - Why are all classes in double?
> - As I understood the order of the parsers matters: earliler ones
> take precendence over later ones?
> - Matching MIME-types are missing completely?
