Some sort of seekability? Also medical data acquisition for data volume intensive modalities effectively has choosen binary. Separating "bulk" from "structured" data will enable using textual XML for the "structured" data. Some application need locality, so "structured" and "bulk" must be multiplexed, as in the multipart/BEEP proposal we have seen some days ago. But this isn't necessarily easier to use than a binary external representation for XML. And in contrast to the proposals of extending XML for binary content, using a binary external presentation for standard XML will be invisible to all newer W3C Recommendations and to all tools which use some sort of layered approach.
