[docbook-apps] Can I link directly to a WebHelp page?

[Xmplar]

I'd like to link into a specific WebHelp page that is formatted in 
frames. I've created SVG graphics with <a href> links, and want to go 
straight to a frameset page created with DocBook WebHelp in oXygen. I 
can link to the home page easily enough (index_frames.html) - is there a 
HTML "target" specification to then navigate to a page in that frameset? 
Or is it possible with Javascript?
