MMI Data Analytics Node extensions for KNIME Workbench version 0.0.14.qualifier by MMI Agency

This node submits URL(s) to W3C CSS Validator service to evaluate quality of the CSS source files. It uses W3C's host http://jigsaw.w3.org/css-validator/validator by default. Note that there is an unpublicized quota limit on W3C's host. Sending a large batch of URLs through this node to W3C's host can result in your IP being banned from their website. To avoid exceeding their quota limit, you should consider setting up your own validator host. You can follow their instruction to set up your own host.
