SIXX is extendable in many ways. Please see the release note:
However, each element in SIXX must be enclosed in <sixx.object ...>
tag. So, probably specially designed XML format would be better for
human readability. Also, SIXX relies on Smalltalk type systems, so the
format is only interoperable among Smalltalks. (We need to translate
class names in SIXX for other languages).
Apparently there are some trade-offs. SIXX is good for developing XML
storage quickly and its data is at least neutral to major Smalltalks.
Anyway, you can try Scribo-Persistence package. It broadly uses SIXX features.
