<h3>Disambiguation Pattern</h3>

<p>Though specification authors may make exceptions to this pattern, the following rules were used to disambiguate names and case of the IDL attributes listed above.</p>

<ul>

<li>Any attribute name referencing concepts that are combinations of two or more words (such as "described by") becomes a camel-cased IDL attribute capitalizing each word boundary. For example, <pref>aria-describedby</pref> becomes <code>ariaDescribedBy</code> with both theD andB capitalized.</li>

<li>Any attribute name referencing concepts that are combinations of two or more words (such as "value text") becomes a camel-cased IDL attribute capitalizing each word boundary. For example, <pref>aria-valuetext</pref> becomes <code>ariaValueText</code> with both theV andT capitalized.</li>

<li>Likewise, any attribute name referencing concepts that can be hyphenated (such as "multi-selectable") becomes a camel-cased IDL attribute capitalizing each hyphenation boundary. For example, the only valid spelling for "multi-selectable" is hyphenated, so <pref>aria-multiselectable</pref> becomes <code>ariaMultiSelectable</code> with both the M and S capitalized.</li>

<li>When trusted dictionary sources list both hyphenated or non-hyphenated spellings (e.g. "multi-line" and "multiline" are both valid spellings) use the hyphenated version and apply the hyphenation rule above. For example, <pref>aria-multiline</pref> becomes <code>ariaMultiLine</code> with both the M and L capitalized.</li>

<li>If all trusted dictionary sources list a single spelling of a compound word with no spaces or hyphens, only the first letter of the term is capitalized. For example, neither “place-holder” nor “place holder” are considered valid spellings of the term “placeholder,” so <pref>aria-placeholder</pref> becomes <code>ariaPlaceholder</code> with only the P capitalized.</li>
