Possible alignment of @style and @render

kerstarno commented 5 years ago

Both, EAC-CPF and EAD3, use an attributes allowing "to specify a rendering style for string" (EAC-CPF) respectively to control "the formatting of the content of an element for display and print purposes" (EAD3). However, these attributes currently go by different names: style in EAC-CPF and render in EAD3.

Further conversation:

Needs to include altrender (seems to be available in any element of EAD3 at the moment)
Needs to include the elements, where these attributes are used (<span> for style, <emph>, <foreign>, <title>, and <titleproper> for render)
Generally reconsider the use of formatting elements/attributes in EAC-CPF and EAD3

Potentially also include althead with <head>. For formatting attributes on <table>and its subelements see #8.

Further conversation came to the following conclusions:

We'd still want to provide the ability to specify formatting for part of a larger body of text. Seeing that <emph> with render and <span> essentially do the same thing, the recommendation would be to decide for one of these with an inclination towards using <span>
There still might be necessity for @render with <foreign>, <title>, <titleproper> to allow targeted manipulation. However, seeing that the same could also be accomplished via other ways (e.g. is currently available as a subelement for all of these), we'd recommend being more concise with regard to definitions, examples, recommendations in the documentation.

To follow up:

Provided we'd only use one of <span> and <emph>, there is the question of data type with regard to the attributes currently used with these elements. style recommends W3C CSS, while render comes with a predefined list of values.
Decided to review W3C CSS in this regard to potentially recommend adapted list of predefined values. (for 5 March)

CSS values that may apply to @style/@render:

color (color, initial, inherit)

direction (ltr (left-to-right), rtl (right-to-left), initial, inherit)

font-family (family-name generic-family, initial inherit)

font-kerning (spacing of letters) (auto, normal, none)

font-size (medium, xx-small, x-small, small, large, x-large, xx-large, smaller, larger, length, %, initial)

font-size-adjust (number, none, initial, inherit)

font-stretch (ultra-condensed, extra-condensed, condensed, semi-condensed, normal, semi-expanded, expanded, ultra-expanded, initial, inherit)

font-style (normal, italic, oblique, initial, inherit)

font-variant (normal, small-caps, initial, inherit)

font-weight (normal, bold, bolder, lighter, 100-900 (values at each 100; defines from thin to thick characters; 400 = normal, 700 = bold), initial, inherit)

quotes (quotation marks, single, double, left and right angle quotes)

text-direction-color (color, initial, inherit)

text-decoration-line (none, underline, overline, line-through, initial, inherit)

text-decoration-style (solid, double, dotted, dashed, wavy, initial inherit)

initial = default value inherit = inherits this property from its parent

Summary of today's conversation:

Lean towards EAC-CPF solution
I.e. do not have a list of predefined values - recommend CSS (as a standard dedicated to formatting/style specifically)
Support with documentation/examples in tag library and with schematron extension(s) for validation
