"For every member element with an attribute named 'name' with a value "a json name" it must have a single child

This is difficult or impossible to express in common XML schema languages

It's straightforward in RNG.  Compact syntax version:

define a-json-name = element * {

  attribute name { "a json name" },

  element value {

    attribute type { "Number"},

    xs:decimal

  }

}

It's really only DTDs and XSD 1.0 that can't cope with this sort of thing.
