Yes, just incase this changes your approach, I believe you would need to
compare it as 10 == 01 to have an accurate outcome with your original [if]
idea. I have had to do this type of thing several times. If item-increment was
zero padded, it would help. However without knowing your end application... For
example prefix-alternate & prefix-last may help you as well. As for efficiency,
who knows which is better, but when I do the above i always feel running so
many conditions is such a waste when all you want is to display something once

I had been contemplating having changes made to these but didn't know if anyone
would get use out of it. For example, a tag that ran only once [prefix-once
10]you are number 10[/prefix-once] but doesn't repeat like prefix-alternate.
Infact it could be a attribute for prefix-alternate [prefix-alternate .10] '.'
meaning only once.

This type of thing comes in handy when you need to highlight a specific object,
like as in a calendar.
