Do you mean to leave a blank between the previous block and this block?

  <fo:block space-before="1em">

Do you mean to leave a blank between this block and the next block?

  <fo:block space-after="1em">

In both cases, when that space is at the very beginning or very end 
of a reference area (say a column), the space is discarded.  This is 
very helpful when displaying continuous blocks across multiple columns/pages.

If, however, you are asking about creating an empty line regardless 
of the content of the element, that would be:

  <fo:block><fo:leader/></fo:block>

This is more elegant than using a non-breaking space or other special 
graphic character.  And more elegant than using regular spaces in 
combination with properties that prevent their collapse.

But I am unclear about your question in that you are asking about 
empty lines yet your template is quite obviously adding the content 
of your paragraph to the result tree.

I hope this helps.
