  This call accepts a document describing a check.  That check is
  instantiated with the <code>checkid</code> specified in the URL.  If the
  check exists, but is not under the provided optional <code>path</code> a
  HTTP 403 code is returned.  If the check already exists under the specified
  <code>path</code>, the check is updated to reflect the new configuration.
  The <code>module</code> cannot be changed for existing checks.  All other
  fields can be changed.  All fields are required except the
  <code>disable</code> field; if disable is omitted, it will inherit the
  disable attribute from parents in the tree (use the default setting).
  On success, a HTTP 200 is returned and an XML documented that matches the
  format of the <code>/check/show</code> REST command.
  The input is as follows:
