# NodeValidatorBuilder.common constructor

NodeValidatorBuilder.common()

Creates a new NodeValidatorBuilder which accepts common constructs.

By default this will accept HTML5 elements and attributes with the default UriPolicy and templating elements.

Notable syntax which is filtered:

- Only known-good HTML5 elements and attributes are allowed.
- All URLs must be same-origin, use allowNavigation and allowImages to specify additional URI policies.
- Inline-styles are not allowed.
- Custom element tags are disallowed, use allowCustomElement.
- Custom tags extensions are disallowed, use allowTagExtension.
- SVG Elements are not allowed, use allowSvg.

For scenarios where the HTML should only contain formatted text allowTextElements is more appropriate.

Use allowSvg to allow SVG elements.

## Implementation

    NodeValidatorBuilder.common() {
      allowHtml5();
      allowTemplating();
    }
