"Good" (gd) and "good with warning" (gw) inline xbrl variations.
The warning is issued for any self-closing tag unless: (1) its content model disallows children, or (2) it cannot appear in a schema-valid inline XBRL document followed by a text node.
Elements in category (1) are <ix:relationship/>, <link:schemaRef/>, <link:linkbaseRef/>, <link:roleRef/>, <link:arcroleRef/>, and in the xhtml namespace, <area>, <base>, <basefont>, <br>, <col>, <hr>, <img>, <input>, <isindex>, <meta>, <param>, and <img>.
Elements in category (2) are <td>, <tr>, <thead>, <tbody>, and <tfoot>.
Therefore, among the elements that will generate warnings when they appear self-closed are <ix:continuation/>, <ix:nonNumeric/>, <ix:footnote/>, <ix:nonFraction/>, and in the xhtml namespace <div/>, <p/>, <span/>, <font/>, <b/>, <i/>, <u/>, <ol/>, <ul/>, <li/>, <h1/>, <h2/>, <h3/>, <h4/>, <h5/>, <h6/>, <caption/>, and others.
