[uf-discuss] "type" subproperty in the hCard logo property?

[Brian Suda]

when you include data as base64, you will use the data:// uri that
URI[1] allows for explict description of the TYPE, so that is where
X2V extracts the TYPE data from.

see http://suda.co.uk/contact/ i have a hidden class="photo" with a data URI:

<img clas="photo" alt="my Gravitar"
src="data:image/png;base64,i.....hejwhjkew" />

from that i can extract the TYPE data "image/png" becomes TYPE=PNG

I hope that makes sense.
