The matching is done on one or more of:

   id             origin                      description
   --------       -------------------------   -----------------------------
   ua             env: navigator.userAgent    User agent
   pua/os.family  env: navigator.userAgent    User agent (os.family: parsed with ua-parser)
   pua/os.major   env: navigator.userAgent    User agent (os.major:  parsed with ua-parser)
   ptf:           env: navigator.platform     Platform
   dd:            env: device.diagonal        Device size
   sw:            env: screen.width           Screen width
   sh:            env: screen.height          Screen height
   saw:           env: screen.availableWidth  Screen available width
   sah:           env: screen.availableHeight Screen available height           
   cap:           capability: name            Capability name    
   
 

• Matching topic is defined as:
  

         {topic name="nnn"}
           ...devices...
         {/topic}
       

• Device tag as:
  

         {device name="nnn"}
           ...match...
         {/device}
       

• Verification can be combined with "or" or "and":

         {or [negate="true"]}
           {and [negate="true"]}
             {string id="nnn" match="iPad" type="equals"/}
             {value id="mmm" min="100" max="200"/}
           {/and}
           {value id="abc" min="10" max="20"/}
         {/or}
       

• String matching:
  {string id="nnn" match="string" type="type" [case="false"] [negate="true"]/}
  where type is "equals", "in" (like indexOf or contains), "wild" or "regexp".
  case="false" means case insensitive match.
• Value matching
  {value id="nnn" [min="value"] [max="value"] [negate="true"]/}.
  
• Negation of match
  [negate="true"] on any tag means that the match is negated (boolean NOT).
