candidates of XML elements

In order to simplify the list of elements as a standard,
I think we should choose only important elements from 
the PSLX standard, and add some elements if necessary.
The first candidates would be:

$B$H$j$"$($:!"#P#S#L#X$N;EMM$+$i@dBP$J$/$F$O$J$i$J$$%?%0$r(B
$B%T%C%/%"%C%W$9$k$H$3$m$+$i$O$8$a$?$$$H;W$$$^$9!#:G=*E*(B
$B$K$O!"$"$kDxEY87A*$7!"%7%s%W%k$J$b$N$K$7$?$$$H;W$$$^$9!#(B
$B$"$H!"B?>/!"DI2C$b$"$C$F$$$$$H;W$$$^$9!#$D$^$j!"#P#S#L#X$O(B
$B#O#A#S#I#S$N3HD%7O$H$$$&7A$K$9$k$H$$0F$G$9!#$^$:!"@dBP(B
$BI,MW$J$b$N$O!"(B

First, primitive element which are required for fundamental
definition of planning and scheduling problems are listed.
The meaning of these terms will be described in another mail.

<customer> 
<supplier> 
<item> 
<resource> 
<operation>
<order> 
<lot> 
<task> 
<event>

The next is a relational element which connects
two of primitive elements
$B$"$H!"0J22,(B
