[Zope-CMF] How to limit the number of News Items being displayed

[Steve Spicklemire]

Hi Norman,

	The 'in' tag has the concept of 'orphans' so 'size' is a sort of 
'target' but you'll get more if the number of items left over is 
'small'. You can force orphans to be ignored by setting 'orphan="0"'

 From the  DTML ref:

Note that in the previous example the size of the last batch is six. 
This is because the dtml-in tag has a feature which attempts to prevent 
the display of very small batches by combining them with adjacent 
batches. Normally, if the number of rows in a batch is less than or 
equal to two, then it is combined with an adjacent batch. The orphan 
attribute in the dtml-in tag can be used to provide an alternative 
setting. The value provided in an orphan attribute is the desired 
minimum batch size. The default setting for an orphan attribute is 3 
(three).
