Yes, you can use the excludelayer tag.

I have three sublayers and I just want to exclude one of the sublayer..so this is not going to help me as I do want those other two layers in the legend

OK, that's not supported. It's entered as a possible future enhancement.

How about in Viewer 3.2? Something like this in config.xml:
<layer label="Map" type="dynamic" visible="true" alpha="1"
url="http://.../arcgis/rest/services/my_vector/MapServer" >
<sublayer id="1" label="Asemat"/>
</layer>
And in LegendWidget.xml:
<excludelayer>Asemat</excludelayer>
Does not seem to work...

I did this by adding and if statement to the CreateChildren function in TOCMapLayerItem.as.

I kept a global var of layers and sublayers I wanted and checked against that in the if statement. I did this because my TOC was dynamic. For your case you could just read from a xml and check against it.

Put the if statement around layerInfos.push(layerInfo);

Hope that helps.
