Re: [docbook-apps] Two column body - Span one figure over the wholepage ?

[Fredrik Svensson <fred@ludd.ltu.se>]

Hi.

Read about the span="all" regarding to fo:flow in an earlier email about title
page.

Thanks for the answer, but I have no time to get it to work.
Will see if I can debug it in the future.. 2 columns are nicer than one, and
sometimes you need a wide figure.

Need to get the document out today... will have to go with a ugly 1 column
body.. :)

However I had a problem with the customization layer :

Error at xsl:element on line 87 of
file:/home/fred/docbook/articles/customspan.xsl:
  Attribute xsl:use-attribute-sets is not allowed on this element
Error at xsl:element on line 94 of
file:/home/fred/docbook/articles/customspan.xsl:
  Attribute xsl:use-attribute-sets is not allowed on this element

I just removed the xsl: before xsl:use-attribute-sets on these lines
and it works. (not sure if that is the correct way.)
I use Saxon as XSLT processor.

The fo gets created but fop can not handle it..

I tried it with my customizations and stand alone..

and it ends in a crash
