fVal(feature value) references any element which can be used to represent the value of a feature.

Schematron

<s:rule context="tei:fVal">
<s:assert test="not(tei:* and text)"> A feature value cannot
contain both text and element content</s:assert></s:rule>
<s:rule context="tei:fVal">
<s:report test="count(tei:*)>1"> A feature value can contain
only one child element</s:report></s:rule>
Example
<f name="gender">
 <symbol value="feminine"/>
</f>
Example
<fs>
 <f name="voice">active</f>
 <f name="tense">SimPre</f>
</fs>
Note

If the element is empty then a value must be supplied for the fVal attribute. The content of f may also be textual, with the assumption that the data type of the feature value is determined by the schema—this is the approach used in many language-technology-oriented projects and recommendations.
