The issue is that in:

<xforms:bind nodeset="submit-trigger" readonly="not(valid/LastName =
'true' and valid/FirstName = 'true')"/>

The readonly expression is evaluated relative to the node pointed to
by nodeset. So it will look for a submit-trigger/valid/LastName and
submit-trigger/valid/FirstName. Instead, you can write:

<xforms:bind nodeset="submit-trigger"
readonly="not(context()/valid/LastName = 'true' and
context()/valid/FirstName = 'true')"/>

(You could also use ".." instead of "context()", but I find context()
cleaner. It is more a matter of personal preference.)
