Hi again. Quite proud to say that I found a nice workaround, using a 

In one of the typoScript based sub-elements, I added section 20:
	10 = TEXT
	10.typolink.parameter.current = 1
	10.typolink.returnLast = url
	20.see_also_count.cObject = TEXT
	20.see_also_count.cObject.data = register:see_also_count
	20.see_also_count.cObject.wrap = |+1
	20.see_also_count.prioriCalc = intval

This counts the sub-items and stores the result in the register called 

And then, I created a new field, which is mapped as an attribute of the 
style parameter of the <div> section containing the list:

<field_left_seealso_all type="array">
	<tx_templavoila type="array">
		<title>See also all wrap</title>
		<sample_data type="array">
			<numIndex index="0">Display see also section</numIndex>
10 = TEXT
10.dataWrap = display:none;
10.if.isFalse.data = register:see_also_count
	<TCEforms type="array">
		<label>Display see also section</label>

Hope this will help others...
