[QGIS-Developer] QGIS Desktop as WMS client - purpose of format "Feature"

[Andreas Neumann]

Hi, 

Since 2-3 versions (I think) there is, next to html and text, now a
third "format" in GetFeatureInfo with the name "Feature". 

I wonder why this new format was introduced? What is the idea and what
are the advantages? 

I noticed that not all of the data types work well in this new format.
For some (e.g. Postgis data types) data is shown in mode text and html,
but nothing in "Feature". One such data type are "json" and "jsonb". The
display either an empty string when a text widet is assigned or NULL
when a List or Key/Value widget is assigned. 

Thanks for clarifying the purpose of the third format "Feature". 

Andreas
