DOCBOOK-APPS: Multi-line header problems

Hi,

I have modified my DSSSL scripts (dbcompon.dsl) to allow parts of the
header to be multi-line text ...

What I am getting is a variable amount of space between the two lines ...,
and I cannot seem to control the while space between them.

The two lines are like:


     xxxxxxx
     yyyyyyy

And they appear correctly on recto and verso pages, but on some pages I get:

     xxxxxxx

     yyyyyyy

but on others I get:


     xxxxxxx


     yyyyyyy

And there seems to be no rhyme or reason ...

Regards
