For v0.2.0 we made a more radical change to the tokenizer package.
We added a new syntax to allow attributes to be set with '{}' syntax.
Any valid JSON expression is allowed within the curly brackets (this more
closely matches JSX syntax).
<div data-num={5}></div>
To support proper decoding in the client, attributes now have a an IsJson bool field
which is set to true if an attribute was parsed with the new {} syntax.
If you only need the case-sensitive tokenization for tags/attributes it is
recommended to use v0.1.0 and not v0.2.0.
