Bind attribute types to procedures to check values.
You can add new procedures for better validation
and each procedure has access to the node in which
the attribute occurred as well as the attribute name
and its value.
By default, attributes are checked without regard
to the element they are found on. You have the choice
of making the procedure test which element is involved
or in writing methods for each element which controls
exactly how the attributes of that element are checked.
This latter approach is best for detecting the absence
of required attributes.

Support the <slot> tag (#848) * Support the <slot> tag <slot> was added to the WHATWG HTML5 Living Standard on April 20, 2016. * Also support the slot= attribute Given that the <slot> tag by itself is not too useful, this commit also introduces support for the global slot attribute. * Using ParseBlock for <slot> This is still suboptimal since ParseBlock will make it so that <slot> always expects "Flow content", whereas the spec says that it should have a Transparent content model. In practice, it should allow all the cases that the spec allows for, but it will also allow some cases that the spec does not allow. Notably, if a <slot> tag is found in a Phrasing content (an inline context in libtidy lingo), it will wrongly let Flow content (block tags in libtidy lingo), whereas it shouldn't. But all in all, it's a good compromise.

Any character except a hexadecimal digit can be escaped to remove

Attempt to address issue #352. This patch correctly address the specific issues in #352, but I'm worried that there's some over-reach here. Currently only implemented as a warning, with no switch to turn it off, which maintains current behavior other than the warning. In general, we're treating any string as a complete URL, rather than breaking URL's into component parts. Thus the `IsURLCodePoint()` check includes a few other generic characters that strictly speaking aren't valid codepoints, but are valid as escape characters and delimiters. When addressing #338, I ran into a similar situation in not having a built-in method to separate path components (although a simple generalized solution was good enough in that case). Thus without introducing a new structure and functions to deconstruct a URL into scheme, authority, path, parameters, etc., some variation of this patch will have to be used to address #352.

Attempt to address issue #352. This patch correctly address the specific issues in #352, but I'm worried that there's some over-reach here. Currently only implemented as a warning, with no switch to turn it off, which maintains current behavior other than the warning. In general, we're treating any string as a complete URL, rather than breaking URL's into component parts. Thus the `IsURLCodePoint()` check includes a few other generic characters that strictly speaking aren't valid codepoints, but are valid as escape characters and delimiters. When addressing #338, I ran into a similar situation in not having a built-in method to separate path components (although a simple generalized solution was good enough in that case). Thus without introducing a new structure and functions to deconstruct a URL into scheme, authority, path, parameters, etc., some variation of this patch will have to be used to address #352.
