#95 Error when attribute id contains a special character

[Ondrej Medek]

Hi,

when I have in a ZUL file:

<toolbarbutton label="Benoit Mandelbrot" popup="personal" id="benoit@example.com"/>

then the editors show the error

Multiple annotations found at this line:
- example cannot be resolved to
a type

It's because the id attribute contains @ and the dot. However, the id attribute is right, so the editor should not show any mistakes.
