[NTG-context] Interrupted framebox around text.

I want to set up several framed text passages in my document, where the title of the passage actually interrupts the top line of the box thus: -----My title------------------------------------------- | | | | | Blah blah. | |_________________________________ | I have seen such a configuration in books prepared using other software. Can it be done easily in Context (without involving Metapost etc.)? -- John Culleton Able Typesetters and Indexers http://wexfordpress.com
