Am trying to understand how best to change the title metadata in headertext halfway through a document that has two parts: Constitutions and Regulations. My first attempt (did not work) \startsetups[headertext] \startdocument [metadata:title={Regulations}] \stopsetups \setupheadertexts [ ] [{\getmarking[chapter]\hskip1em \pagenumber}] [{\pagenumber \hskip1em \setup{headertext}}] [ ] My second attempt (quite crass, but it works!!) was to create a second \startdocument within the main \startdocument (obviously closing it towards the end but before the main \stopdocument), this time with [metadata:title={Regulations}] instead of the original [metadata:title={Constitutions}]. However, I have a strong feeling this is not a very elegant solution! Thoughts? Julian
