| <altGrp> | (alternation group) groups a collection of <alt>  elements and possibly
pointers. | 
| Attributes: | | mode | states whether the alternations gathered in this collection are
exclusive or inclusive. |  |  | Datatype: (excl|incl) |  |  | Legal values: | | excl | indicates that the alternation is exclusive, i.e. that at
most one of the alternatives occurs. |  | incl | indicates that the alternation is not exclusive, i.e. that
one or more of the alternatives occur. | 
 |  |  | Default: excl |  | wScale | indicates the scale used to express the value of the
weights  attribute value. |  |  | Datatype: (perc|real) |  |  | Legal values: | | perc | indicates that the weights are expressed as percentages. |  | real | indicates that the weights are expressed as values
between 0 and 1. | 
 |  |  | Default: perc | 
 | 
| Example | <altGrp mode=excl>
  <alt targType='seg seg' targets='dm lt bb' weights='50 25 25'>
  <alt targType='l l' targets='rl db' weights='50 50'>
</altGrp> | 
| Example | <altGrp mode=incl wscale=perc targType='seg l'>
  <alt targets='dm rl' weights='90 90'>
  <alt targets='lt rl' weights='5 5'>
  <alt targets='bb rl' weights='5 5'>
  <alt targets='dm db' weights='10 10'>
  <alt targets='lt db' weights='45 90'>
