[texhax] Nested enumeration.

[Rolf Turner]

I want to produce a nested set of lists numbered in an ``i.j'' style.
I.e. I want something like

	1. Blah.
            1.1 blah
            1.2 blah blah

	2. Blah Blah.
	   2.1 blah
            2.2 blah blah
            2.3 blah blah blah

	3. Blah Blah Blah
		<etc>

The package ``enumerate'' does not, as far as I can gather, provide this
sort of ``within'' numbering.

The package ``chngcntr'' almost does what I want; if use this package  
and
issue the command \counterwithin{enumii}{enumi} I get the desired result
except that the item numbers in the sublists are enclosed in  
parentheses.
I.e. I get ``(2.1)'' rather than ``2.1''.

Is there any (simple! --- I'm not a very good tex-hacker!) way of
suppressing these parentheses?

		cheers,

			Rolf Turner
