SYMBOL

Symbolic variable. Some numeric or string quantities may have to be represented by a symbolic variable rather than an explicit value. SYMBOL is an experimental approach towards this and the details have not yet been worked out.

Hypothetical... Suppose two objects are contrained to have numerical values which sum to a constant value (e.g. the occupancies of two or more atoms must sum to 1.0). We might write:
<SYMBOL NAME="C13occ">0.73</SYMBOL>
and later
<XVAR TYPE="symbol" NAME="pos1">C13occ</XVAR>
<XVAR TYPE="symbol" NAME="pos2">1-C13occ</XVAR>
