discuss whether (how much) XDI syntax should be exposed to the user

card addresses look like this: **=markus#home**
attributes look like this: **<#first><#name>**

how much of this should be visible in the UI?
probably depends on audience

should there be a "simple" and a "developer" mode?

should we show "nice" words in the UI, and have the "XDI syntax" in hover-able tooltips?
