Hi Gerard,

thank you for helping, but, excuse me, but I think you didn't hit the 
point I'm fiddling with:

Let me illustrate what I want to achive:

I'd like to be able to use 'soft line-wraps' inside a paragraph, for two 
sentences that deal with the same idea, meaning they should be put into 
_one_ paragraph, but that are far too long for comfortable reading.

And I would not like to fiddle around with any limitation of 80 
characters, because that would IMHO make the page look rather ugly in 
windows of a different width or in formats like pdf or similar.

I had to realize that appearently I can't state a definite line-break in 
docbook-xml, except for the technique you mentioned:
	<para><literallayout>{many lines of text,
	where every line is to be _less_ than
	80 characters long}</literallayout></para>

I'd like to use them as:
	<para>{some few sentences}<literrallayout>
	</literallayout>{another few sentences}</para}.

If I use these two tags like I would like to be able to the result 
shows, at least on my system, the disadvantage of not only one 
'linebreak' but one double break for _both_ tags, meaning space of 3 
empty lines between the sentences that are to be seperated!
	{some few sentences}<double-linebreak>


	{another few sentences}
-> This is more than I would have gotten by starting a new paragraph!

Appearently, if <literallayout> isn't put directly after the <para>, the 
tag implies one double-lined linebreakbreak _before_ it.

Could this be avoided anyhow?
Could it be possible that we could the used definitions in a more 
optimal way?

Personally I do not have the time to become an expert of docbook / xml / 
sgml as you are, but, could you do me the please and help me out?

BTW, what is your policy on using tags?

Am I to use any tag that fits into the actual used context, or , the 
delimited choice that is mentioned in conventions.xml?

If we consider <tagA> and <tagB> to cause the same effect, am I to use 
<tagB>, that would be semantically correct in the actual context, or 
<tagA>, that's already mentioned in conventions.xml?

When I asked Mark, he told me to use any tag, but to use as few as 
possible, what the policy you practice?

OK, I hope I've been able to make my intention a bit clearer,
thanks in advance for your help,


PS: For Mark: Sorry for being not content with your advice,
I still do not feel comfortable with preferring simplicity for 
semantical correctness.

PPS: Did you know that <emphasis><literallayout>
</literallayout></emphasis> create an empty footnote?
