A lot of this depends on the specifics of what you are trying to achieve.
As an example - I use the misc text field to hald an xml snippet something like this :-
Code:
<Data>
<Delivery></Delivery>
<DeliveryMax></DeliveryMax>
<Old></Old>
<field1></field1>
<field2></field2>
<field3></field3>
<field4></field4>
<field5></field5>
<additionalinfo></additionalinfo>
<msds></msds>
<tech></tech>
<video></video>
<link1></link1>
<link1text></link1text>
<Social1></Social1>
<Social2></Social2>
</Data>
It's then trivial to get at this data from your xmlpackage with either a modification to the query or an additional query.
You can also import this field from the normal excel import.
