Variables reserved for dynamic insertions

:ins_align
dynamic insertion
defines the manner in which the inline picture
  is aligned with respect to the line. Possible values: bottom, middle or top.
  Default is empty (which means bottom).

:ins_attr
dynamic insertion
is used to define miscallaneous attributes of a
  dynamic insertion. Examples:
  <pre>  ins_attr = alt="meaning"</pre>
  or
  <pre>  ins_attr = align=middle</pre>
  (aligns the middle of the image with the baseline for the current
  textline), or
  <pre>  ins_attr = ismap</pre>
  (coordinates of the click will be passed back to the server; if the link
  of the element is the wims server, the coordinates will be registered
  under the variable ``no_name''.)

is used to define border width of the html
  element ``IMG '' resulted from the dynamic insertion. Its value should be a positive

dynamic insertion
