=== Links and markup ===
Linking and wikimarkup should be done {{em|outside}} the template when possible:
* Right: <code>{{bxt|<nowiki>'''[[Foo|{{dfn|Foo}}]]'''</nowiki>}}</code>
* Wrong: <code>{{!bxt|<nowiki>{{dfn|'''[[Foo]]'''}}</nowiki>}}</code>

The <var>term</var> content in the first parameter {{em|can}} be marked up with wikimarkup or HTML, at the <code>inline</code> level, such as italics, superscript other text-formatting code (versus <code>block</code>-level elements, such as paragraphs, tables, block quotations, and so on), if absolutely necessary. {{em|If this is done, the {{para|title}} parameter {{strong|must}} contain the un-marked-up, plaintext term.}} Example: The displayed text (first parameter) uses superscript markup, for accessibility reasons, while the real plaintext in the title parameter uses a Unicode character entity (doesn't count as wikimarkup) for a superscripted 2, which is actually more correct but may not display properly on older systems:
:<code><nowiki>{{dfn|1=E=MC<sup>2</sup>|title=E=MC&amp;sup2;}}</nowiki></code>
yields:
:{{dfn|1=E=MC<sup>2</sup>|title=E=MC&sup2;}}
while this:
:<code><nowiki>{{dfn|1=E=MC<sup>2</sup>|2=Mass&ndash;energy equivalence; E is energy, m is mass, and c is the speed of light in a vacuum|title=E=MC&amp;sup2;}}</nowiki></code>
gives:
:{{dfn|1=E=MC<sup>2</sup>|2=Mass&ndash;energy equivalence; E is energy, m is mass, and c is the speed of light in a vacuum|title=E=MC&sup2;}}
Note that in the first case, the mouse hover tooltip is the Unicode version of the <var>term</var>, as given in the {{para|title}}, while in the latter it is the <var>definition</var> given in the {{para|2}} parameter.

Linked version:
:<code>[<nowiki />[Mass–energy equivalence|{{tnull|dfn|1{{=}}E{{=}}MC<sup>2</sup>|2{{=}}Mass&ndash;energy equivalence; E is energy, m is mass, and c is the speed of light in a vacuum|title{{=}}E{{=}}MC&amp;sup2;}}]<nowiki />]</code>
gives:
:[[Mass–energy equivalence|{{dfn|1=E=MC<sup>2</sup>|2=Mass&ndash;energy equivalence; E is energy, m is mass, and c is the speed of light in a vacuum|title=E=MC&sup2;}}]]
It still has a dotted underline indicating a tooltip, but is also a bluelink. Mouse hovering shows both the tooltip and, in the status bar, the target URL, in browsers that support these features.

Link inside the {{tnull|dfn}}:
:{{tnull|dfn|1{{=}}[<nowiki />[Mass–energy equivalence{{!}}E{{=}}MC<sup>2</sup>]<nowiki />]|2{{=}}Mass&ndash;energy equivalence; E is energy, m is mass, and c is the speed of light in a vacuum|title{{=}}E{{=}}MC&amp;sup2;}}
results in:
:{{dfn|1=[[Mass–energy equivalence|E=MC<sup>2</sup>]]|2=Mass&ndash;energy equivalence; E is energy, m is mass, and c is the speed of light in a vacuum|title=E=MC&sup2;}}
This doesn't mess up the page, but the <var>definition</var> fails and there's no tooltip cursor, meanwhile the markup is hard for other editors to understand anyway so it is {{strongbad|deprecated}}.

Links, HTML, wikimarkup, and other markup <strong>cannot</strong> be applied to content in the {{para|2}} (<var>definition</var>) parameter, nor in a {{para|title}} parameter, only plain text and character entity references ("&-codes", like <code>&amp;quot;</code>).
