    <blockquote> <p>If there is no DTD or schema to validate the H5 document against, how are we supposed to do document validation? And by document validation, I mean "how are we supposed to ensure our html5 documents are both syntactically accurate and structurally sound?" Please help! This is going to become a huge problem for our industry if we have no way to accurately validate HTML5 documents!</p> </blockquote> <p>If testing pages with either Firefox or Opera, both of those will report errors such as code that is not "well-formed" and mismatched tags. Beyond that, one of the validators such as validator.w3.org or validator.nu will definitely help.</p> <blockquote> <p>Sure, the W3C has an online tool that validates individual pages. But, if I'm creating A LOT of pages (hundreds, say) and I want to validate them in a sort of batch mode, what is the accepted method of ensuring valid structure and syntax? I mean, it seems rather rudimentary to just look at the document and say "yep. that's a valid xml document."</p> </blockquote> <p>There are ways to run the W3C validator in batch mode.</p> <blockquote> <p>What about custom tags? What about tag attributes? It seems like the W3C is leaving us out in the cold a little bit here.</p> </blockquote> <p>The easy answer to that one is that "custom tags" are simply <strong>not</strong> considered valid. The Working Group has thoroughly addressed the issue of "distributed extensibility", particularly with respect to allowing "decentralized parties to create their own languages" and "extension attributes" (http:// lists.w3.org/Archives/Public/public-html/2011Feb/0085.html). There are numerous ways to extend HTML (http://www.whatwg.org/specs/web-apps/current-work/multipage/infrastructure.html#extensibility) but adding custom tags is <em>not</em> one of them. Custom data and microdata attributes should validate fine.</p> <blockquote> <p>Maybe the answer is "wait for HTML5 to become official". But I really can't wait for that. I need to start creating and validating content now. I have applications I want to publish that can only be accomplished with html5.</p> </blockquote> <p>Since HTML 5 was stabilized at the end of last year (Dec. 2010), IMO we don't need to wait for it to become an official "recommendation" by the W3C. The stabilized spec provides a solid base that all browser vendors can implement consistently and for the ongoing evolution <em>beyond</em> HTML 5 of the spec, which is now being called the "HTML Living Standard" (Jan. 2011 and later). There is a good diagram of this at <a href="http://www.HTML-5.com/html-versions-and-history.html#html-versions" rel="nofollow">http://www.HTML-5.com/html-versions-and-history.html#html-versions</a> (scroll down to see the diagram).</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
