Thanks for ConTeXt, it is an amazing system.
The following test case demonstrates the bug.
\usemodule[mathml]
\starttext
\xmlprocessdata{}{
<?xml version="1.0" encoding="utf-8"?>
<foo xmlns="http://www.example.com/ns/foo" xmlns:m="http://www.w3.org/1998/Math/MathML">
<m:math version="2.0">
<m:apply><m:union/><m:ci>a</m:ci><m:ci>b</m:ci></m:apply>
</m:math>
<m:math version="2.0">
<m:apply><m:selector/><m:ci>a</m:ci><m:ci>b</m:ci></m:apply>
</m:math>
</foo>
}{}
\stoptext
No output is produced. This has been verified with live.contextgarden.net.
In order for output to be produced, <m:union/> must be changed to <union> and
<m:selector/> must be changed to <selector/>, but these are in the wrong
namespace in this context. In other words, this bug applies to the keyword
element in an apply element.

in x-math.mkiv search for
\startxmlsetups mml:apply
and replace this bit:
\edef\mmlapplyaction{\xmlfilter{#1}{/*/tag()}}
\doifelsesetups {mml:apply:mml:\mmlapplyaction} {
\xmlsetup{#1}{mml:apply:mml:\mmlapplyaction}
} {
\xmlsetup{#1}{mml:\mmlapplyaction}
}
(btw, isn't content mathml more fun than presentation mathml?)

Works nicely. For <eq/> I also had to change this part from name() to
tag():
\startxmlsetups mml:relation
\edef\mmlapplyaction{\xmlfilter{#1}{/*/tag()}}
\MMLcreset \xmlsetup{#1}{mml:relation:\xmlattdef{#1}{align}{\MMLrelationalign}}
\stopxmlsetups

can you also check
\startxmlsetups mml:apply:inverse
\settrue\xmlinversefunction
\xmlsetup{#1}{mml:\xmlfilter{#1}{/mml:apply/*[2]/tag()}}
\stopxmlsetups
