Thanks.

Here is another bug.  JamesC's implementation correctly reports validity, but 
PyTREX 0.7.1 does not.  If you do not create an automaton, you have to 
backtrack a lot.

1) pattern

<element name="foo">
<optional>
<optional>
<optional>
<optional>
<optional>
<optional>
<optional>
  <element name="a"><empty/></element>
</optional>
<element name="a"><empty/></element>
</optional>
<element name="a"><empty/></element>
</optional>
<element name="a"><empty/></element>
</optional>
<element name="a"><empty/></element>
</optional>
<element name="a"><empty/></element>
</optional>
<element name="a"><empty/></element>
</optional>
</element>

2) document

<foo><a/><a/><a/><a/><a/><a/><a/></foo>

Cheers,

Makoto
