That worked in Squeak 3.4 and in Squeak 3.6.

I did the example step-by-step with 3.6 and with 3.7
and found that  XMLTokenizer>>nextLiteral was changed.
In earlier versions, we had
  validChars := ':-_.' asSet.
Now we have a class variable LiteralChars that is an array
of boolean values. The value at position  " asciiValue + 1 "
tells us whether the ascii value is a literal char. In the class
this variable LiteralChars is initialized, but regrettable under
the assumption that array indices begin with 0.
That is a bug and its consequence is that the literal
xml:stylesheet is not correctly read.

The attached change set is an attempt to fix the problem.
As the mistake is clearly identified, I think that it should not
be difficult to review the fix. However ...

... Uses of class variables NameDelimiters  and  DigitTable  are

   (NameDelimiters at: char asciiValue)
   (DigitTable at: char asciiValue)

This assumes an index range from 0 to 255 and will inevitably
crash when the character (Character value: 0)  is ever read.

I fixed that, too - call me a pedant if you think I am one!
(The fix is in the class initialization and in the methods that
access the class variables).

By the way: Squeak has a class  CharacterSet which implements
what tokenizers need: character sets.

You are right, but for tests I need more time. Mind that I am
not very experienced with XML; I used that code once to
file in an electronic dictionary, that was all.
