How to specify an attribute-set?

[Trevor Harmon <trevor@vocaro.com>]

Hi,

I'm using DocBook XSL to transform a DocBook file to FO, and I'm  
customizing the output via user-configurable parameters [1]. For  
instance, if I want to prevent URLs from appearing after the text of  
a ULink, I can set the ulink.show parameter [2].

Specifying these parameters is easy enough. When using Ant's Xslt  
task [3], for instance, I can simply add <param> sub-elements.  
Likewise, when calling Saxon from the command line, I can just add  
the parameters as command line arguments.

I recently discovered that some of the FO parameters, such as  
formal.title.properties [4], are not so simple; they're structured.  
That is, instead of a key/value pair, they're specified as an  
attribute-set. How is one supposed to specify these attribute-sets  
when using Ant or Saxon? I couldn't find any documentation or  
examples on how to do this.

Thanks,

Trevor
