Accessing tag attribute information

Hi, 

Is there an easy way to access the OSM feature attribute information using Elk? Specifically I would like to be able to represent sidewalks, which are typically tagged as an attribute of highways using sidewalk = right/left/both, and street names.

Forgive me if this question has been answered, I'm relatively new to Grasshopper and Elk and poked around for a while and couldn't find anything.  

Thanks!

Jess

Any information found in tags should appear in the Feature Key (K) output of the OSM Data component. It's up to you to filter out the data based on the key you want.  Here's an example of me looking for any highway data that has a tag that mentions 'sidewalk'.
