Pretty-printing HTML and FO output

[andy.hatton@oracle.com]

Hi

For general debugging purposes I want to be able to indent/pretty-print 
my output, both HTML and FO. Particularly with the FO files, the lines 
are extremely long and it makes opening the FO file in an editor painful.

For the HTML I know I can use an <xsl:output indent="yes"/> element in 
my customization layer as this is supported by my XSLT processor, but I 
also saw that there's the chunker.output.indent parameter. The 
parameter's name seems to imply that it would only work if you use the 
chunking stylesheets. I also noticed that <xsl:output indent="no"/> is 
exlicitly set in html/docbook.xsl. Can someone clarify whether I can 
override that in the customization layer?

For FO, I noticed the following comment in fo/docbook.xsl

<!-- It is important to use indent="no" here, otherwise verbatim -->
<!-- environments get broken by indented tags...at least when the -->
<!-- callout extension is used...at least with some processors -->
<xsl:output method="xml" indent="no"/>

Can anyone shed any light on this comment?

Thanks
