Extend the Silk format to allow intermediate nodes between tab-separated data

Please describe a summary of the new feature (in a paragraph):

It would be nice if Silk format supports intermediate data between
tab-separated data description. For example, 

-user(id, name)|
1 leo
2 yui
 -note: my son
3 apple

This data description corresponds to the following JSON:

{"user": [
 {"id":1, "name":"leo"},
 {"id":2, "name":"yui", "note":"my son"},
 {"id":3, "name":"apple"}
]}

Please provide any additional information below:
