DOCBOOK-APPS: Labelling of figures

Hi,

In an <article>, I notice that any <figure>'s are labelled numerically, 
incrementing for each consectutive figure in the document. Is it possible 
to have numbering restart for each <section>, so that figures are labelled 
e.g. Figure 4.1 for the first figure in the fourth section, using DSSSL?

Cheers,
