On the contrary, James says explicitly that one of the virtues of MicroXML
is that if you take a document that is both well-formed MicroXML and valid
against a suitable schema, you guarantee that it is also valid HTML5.
Such a document is both processable by all the facilities available
for XML documents, and guaranteed to be renderable by an HTML5 browser
without further down-translation.

I de-emphasized this use case in my SD Times interview, but it's a
perfectly realistic one.

Indeed.  I have attempted to position MicroXML as complementary to JSON
and interoperable with it, rather than a competitor of any sort.

But the complexities of Unicode are for the most part the complexities
of the real world of writing as it exists.  If we fix a single encoding
(UTF-8), and we strongly recommend a single normalization form (NFC),
then the complexity that remains reflects the complex history of writing
systems in all their hair.

As for schema validation, my intention with MicroLark is to package an
Examplotron validator with it.  Schema languages don't get much simpler
than Examplotron, and it is defined in terms of RELAX NG, so its
design is more sophisticated than it looks.
