I'm submitting a bug report

• Library Version: 1.0.1

Please tell us about your environment:

• Operating System: Windows 10
• Node Version: 5.1.0
• NPM Version: 3.5.0
• JSPM OR Webpack AND Version none, I'm using AureliaCLI
• Browser: Chrome 51
• Language: TypeScript 1.9

Current behavior: pattern attribute binding not work fine. If value is undefined aurelia sets pattern="undefined" and input is always invalid. minlength and maxlength attribute binding sets 0 if binding source is null or undefiend.

Expected/desired behavior: You can see a demo here: http://plnkr.co/edit/pLIM83?p=preview

• What is the expected behavior? If source of pattern binding is undefined, aurelia shouldn't set pattern attribute, like required. The same for minlength and maxlength.
• What is the motivation / use case for changing the behavior? You can build custom inputs elements and enable to set or not validations attributes.
