Inline Elements

Inline elements are HTML elements that should be treated as codes embedded within a run of text, for example <b>, <em>, etc.

The following HTML elements should be treated as inline codes:

HTML DTD 'inline' elements: fontstyle: <tt>, <i>, <b>, <big>, <small> (+ deprecated: <strike>, <s>, <u>, <font>)
phrase: <em>, <strong>, <dfn>, <code>, <samp>, <kbd>, <var>, <cite>, <abbr>, <acronym>.
formctrl: <input>, <select>, <textarea>, <label>, <button>.
special: <a>, <img>, <object>, <br>, <script>, <map>, <q>, <sub>, <sup>, <span>, <bdo>.
and also: <ins>, <del>.

[Not sure how to treat 'specials': <script> is generally not seen as inline by translation tools... Also: <object> can have non-inline element (???)]

[Get a list of the practice in commercial tools. Default inline tags for TagEditor are not the same. How about SDLX, DejaVu, etc.? Need for a standard list of inline tags?]

Ambassador: a, abbr, acronym, b, basefont, bdo, big, blink, cite, code, dfn, em, font, i, img, kbd, nobr, q, s, samp, small, span, strike, strong, sub, sup, tt, u, var, wbr (+br optionally)

Default for Catalyst: h1, h2, h3, h4, h5, h6, code, img, i, b.

Rainbow 4: b, i, span, br, font, a, img, big, small, tt, em, strong, dfn, code, samp, kdb, var, cite, abbr, acronym, q, sub, sup, bdo, u, s, strike, blink, applet, iframe, del, ins, ruby, rt, rc, rp, rbc, rtc.

IMPORTANT:

There is several strategies possible for inline codes:

• using <bpt>, etc.
• using <g>, etc.

The second use allows to keep an open-close structure that is reflected in the DOM tree. While <bpt>, etc. does not.
