This issue ensures that the fix properly warns for the following:

• The style attribute in the paragraph tag has three closing quotes, and the name has an extra closing quote. This should generate a warning for each extra quote (todo: only warn once, and indicate the name of the attribute).
• Both is and id should report missing quotes.
• Tidy will not notice that the value for id is "midnight shows", and will create a new attribute called shows, which is reported as being proprietary.
