<bold>
Bold
Used to mark text that should appear in bold face.
Remarks
Emphasis as a Toggle Switch:
The @toggle attribute controls the behavior of this element. When the value of @toggle is set
to “no”, the emphasized text remains in the requested style, no matter what the surrounding text does. When the value of @toggle
is “yes”, if the surrounding text is set to the same
emphasis style, the text within this element will change to another emphasis style, so that the text will always
be typographically distinct from its surroundings.
Using the element <italic> as an example, setting
the @toggle attribute to “no” would mean that a material marked as italics will always be italics, even in an italic context. In contrast, if the @toggle attribute was set to “yes” on the <italic> element, if the formatting context imposes italics (whether due to another <italic> element, a stylesheet, some CSS, or other means), then the
italics would be turned off within that context, making the emphasized text emphasized by contrast, but not italic. The <italic> element would still produce italics everywhere else.

Example 1
... <p>... The third nucleotide (CG<bold>A</bold>) at codon 529, which is a specific nucleotide of <italic>M. tuberculosis</italic> (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B11">11</xref>), was not clearly determined by conventional PCR direct sequencing. Furthermore, PCR sequencing misidentified codon 531 as T<bold>C</bold>G, which reflects the rifampin-susceptible strain. However, the second nucleotide at codon 531, which is the most frequent site of mutation related to rifampin resistance, was determined as T<bold>T</bold>G by nested PCR sequencing (Fig. <xref ref-type="fig" rid="F5">5</xref>, lower panel). ...</p> ...
