To me, the definition of your restriction is difficult to understand. But this
sentence helps me to have some guess.
XML Schema and RELAX Core have the same restriction: when you declare some content
model is "mixed", not only whitespace characters but also non-whitespace characters
are allowed to prepend, intersperse, and follow elements. TREX is slightly more
powerful in the sense that you can specify where in the content model <anyString>
occur. For example, (a, #anyString, b, c, #anyString) is possible in TREX, but
XML Schema and RELAX Core only allows (#anyString, a, #anyString, b, #anyString,
c, #anyString). This is not quite it, since TREX allows <attribute ....> as part of
content models. But this is basically the difference. Am I right?
