I tell my students to use a leader to get fixed or horizontal space in a line:

    <fo:leader leader-length=".5in"/>

This has the benefit of looking like a bunch of spaces, without 
acting like a bunch of spaces.

But that is a fixed space ... it isn't a space into which you can place text.

XSL-FO defines the <fo:inline-container> for defining a 
specifically-sized container on a line into which you could place a 
block of text, thus giving you a constant start position on the prose 
of your paragraph ... but my recollection is that the current version 
of RenderX doesn't support inline containers.  That appears to still be true:

   http://www.renderx.com/reference.html#Formatting_Objects

... in which case I tell my students to use a side float.

Probably because of some kind of rounding or placement issues with 
the height of the float on the first line that prevents the second 
line from going to the start edge.

>Here's some example FO:

Thank you for sending the example, as that made it easy to test some 
ideas, and sure enough, adding the following to the block prevents 
the second line from going to the start edge:

    line-height="1"

As I suspected, the leading of the block inside of the float is big 
enough to trigger the apparent indentation of the second line.  By 
removing the leading (using a line height scalar value), there is now 
room for the second line to go to the edge.

I hope these ideas help.
