Is it possibly to get Index Components?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. for Index ^FTAS


What is the expected output? What do you see instead?
Is it possible to get all the components of an index?

using YQL it only lets you get the first 51 but there are 661 stocks in this 
index.

I couldn't see anything in the API docs about components but wondered if there 
was an easy way to achieve this?

Suggestions to fix the defect?
Could we add elements for this so when you get an INDEX object you have 
components etc attached.
