I'm having problems with a DTD that is a modified version of an example in
the W3 schools DTD tutorial.

Problem is WDSC and the only on-line validator I can find both say it is
invalid and I cannot for the life of me see why.

Apologies if there is a dumb mistake in this - I've tried so many version
now ...

<!DOCTYPE Tools[
<!ELEMENT Tools (Product+)>
<!ELEMENT Product ( #PCDATA , Description , Quantity? , SellPrice  ) >
<!ELEMENT Quantity ( #PCDATA ) >
<!ELEMENT SellPrice ( #PCDATA ) >
]>
<Tools>
                <Product>00020
               <Description>This is the description </Description>
                   <SellPrice> 20.00 </SellPrice>
                </Product>

                <Product>00001
                   <Description>A Christmas gift </Description>
                   <SellPrice>95.00</SellPrice>
               <Quantity> 125 </Quantity>
                </Product>
</Tools>

What this should represent is that there are multiple Products each of which
contains PCDATA plus a Description, Price and an optional Quantity.

If I change this line:
<!ELEMENT Product ( #PCDATA , Description , Quantity? , SellPrice  ) >

To this:
<!ELEMENT Product ( #PCDATA | Description | Quantity? | SellPrice  )* >

Then it validates and WDSC accepts it - but is seems such a kluge to me and
I suspect results in more elements being optional than I intend.
