[NTG-context] Referencing a Document within the same Project

Hi all, I am designing a document suite consisting of two dozen or so documents that are all interrelated. I was wondering whether there is a way that I can define a reference point for an entire document within a project and then refer to that from another document, like \document{global-definitions-document} % This is fictitious syntax ...in one document and then refer to that in another document: For global definitions, please see \about{global-definitions-document}. ...or something along those lines. Regards, Malte.
