labels/descriptions. Addresses w3c#88

Add guidance on Unicode code point order.

@r12a

Add a reference to 4647 when talking about BCP47 Also moved requirements above explanation per our standard (thanks @r12a)

Mention of using the language subtag registry instead of making your own list. Also some cleanup of the language tagging of the Arabic examples.

index.html

This resulted in a bit of a rewrite. In addition, I added links to the "choosing a language tag" article, Richard's language subtag lookup tool, and the registry itself.

A couple of browsers don't seem to display the "fixed" bidi example correctly, at least when respec runs on it. Switching to markup, which is effective. Also rewrite the "notice how" paragraph to be (hopefully) clearer.

- made the example text larger to make the color mixing clearer - simplified the description of the mixing problem

- Removed the charmod reqs altogether - Added a "warning" box about find being hard and linking our string-search doc

I noticed that Netlify wasn't working. It seems like someone revoked access to all W3C repos (not just the i18n ones). I'll try to add it back.

- Removed extreneous link to specdev? - Described matching in terms of ranges rather than subtags (4647 is not about matching subtags) - Cleaned up description of 5656, including mentioning the LSTR

Made the example clear that the code units are in the UTF-16 character encoding.

@r12a

- Added a requirement not to concat strings! - Added a "seealso" suggested by @r12a - Added explanation of the Note example - Minor wording changes in the colorful example.

I don't think people will find this general advice about composite messages, that has nothing to do with text direction.

I think it is best to move the section "Composite Strings" under 'Text-processing" and then add a 'see also' to the text direction section 3.6.

Rather a complicated and long sentence.

How about:
When a specification requires an implementation to create or generate text which will be displayed to users, the specification should provide implementers with guidance on
how to avoid potential problems related to text direction.

+</div>
+
+<p>Specifications for APIs, protocols, or document formats sometimes require an implementation to create or provide a field containing a display name or description. When such a string is assembled from separate parts, it can result in problems with presentation or understanding due to the way that the <cite>Unicode Bidirectional Algorithm</cite> [[UAX9]] processes the assembled string. In such cases, the specification should guide implementers about how to create values that will display properly.</p>


Several things are unclear to me here, and rather than provide text suggestions that may be barking up the wrong tree, we should perhaps discuss during our telecon. Questions include:

do you mean bidrectional text or text that generally runs in a particular direction (eg. RTL)?

i suspect, but i'm not sure, that we are talking solely about strings that contain bidirectional text within them, or about correctly displaying any string that is inserted into a target location by the consumer?

if the latter, we're focusing on what producers need to do, we should mention dirname or using other metadata

Basically, i think we need a little more clarity about the role of producers vs consumers, and in-string direction vs how a string will be inserted into a target location. It seems a little vague at the moment. The section title, Concatenation of Strings, doesn't make it sound like we're concerned with string internal direction, but rather strings being inserted into the target location. The example shows one scenario that fits the section title, but the preceding text needs to be clearer before we get to the example, and needs to clarify whether we are also talking about string-internals.

Numbers and dates are only easy to sort if you compare internal representations of the data.

As a warning about string searching this seems a little oddly placed here. I think that similar difficulties apply to matching strings for sorting, but i think it would be useful to couch this warning in those terms.

This section is (and has historically been) called "specifying sort and search functionality". All of the prose in the section is about sorting. This is the only mention of "search"--I added it so that we wouldn't have a gap. I think maybe a subsection div above it would help. I also retitled as "under construction". See the new PR

Can we use a rem or, if necessary, an em unit rather than pt? If you really want to fix the size, perhaps use px rather than pt.

Done. Made it 300%
