Use the str-split-to-lines template (file strstrSplit-to-Lines.xsl)
from the FXSL functional programming library.

It is based upon a functional tokenizer, which given a text and a set
of possible delimiters for words  produces a list of words. 

Thus the str-split-to-lines template can easily be modified to produce
justified text by distributing the necessary number of additional
spaces between the words that form a line.

The FXSL functional programming library can be used with the Saxon,
MSXML and Xalan XSLT processors and can be easily customised for other
XSLT processors. It is freely available at:
