Should spec constants be uppercased by build rather than CSS?

[gibson042]

It's a bit odd that text at e.g. NormalCompletion has a step that looks like "Return Completion Record { [[Type]]: NORMAL, [[Value]]: value, [[Target]]: EMPTY }." but copies as "Return Completion Record { [[Type]]: normal, [[Value]]: value, [[Target]]: empty }." (because text-transform "has no effect on the underlying content, and must not affect the content of a plain text copy & paste operation").

It would probably reduce surprise (and increase the value of copy–paste interactions for purposes such as test262) to perform uppercasing at build time such that it is part of the resulting HTML source:

-{ <var class="field">[[Type]]</var>: <emu-const>normal</emu-const>, <var class="field">[[Value]]</var>: <var>value</var>, <var class="field">[[Target]]</var>: <emu-const>empty</emu-const>&nbsp;}
+{ <var class="field">[[Type]]</var>: <emu-const>NORMAL</emu-const>, <var class="field">[[Value]]</var>: <var>value</var>, <var class="field">[[Target]]</var>: <emu-const>EMPTY</emu-const>&nbsp;}

The alternative is for them to copy as ~empty~, with tildes added in, to better match the source rather than the display. See #550.

Ah yeah, that's probably better.
