/**
* Add an inflectional variant to this word element. This method is intended
* for use by a <code>Lexicon</code>. The idea is that words which have more
* than one inflectional variant (for example, a regular and an irregular
* form of the past tense), can have a default variant (for example, the
* regular), but also store information about the other variants. This comes
* in useful in case the default inflectional variant is reset to a new one.
* In that case, the stored forms for the new variant are used to inflect
* the word.
*
* <P>
* <strong>An example:</strong> The verb <i>lie</i> has both a regular form
* (<I>lies, lied, lying</I>) and an irregular form (<I>lay, lain,</I> etc).
* Assume that the <code>Lexicon</code> provides this information and treats
* this as variant information of the same word (as does the
* <code>NIHDBLexicon</code>, for example). Typically, the default
* inflectional variant is the <code>Inflection.REGULAR</code>. This means
* that morphology proceeds to inflect the verb as <I>lies, lying</I> and so
* on. If the default inflectional variant is reset to
* <code>Inflection.IRREGULAR</code>, the stored irregular forms will be
* used instead.
*
* @param infl
* the Inflection pattern with which this form is associated
* @param lexicalFeature
* the actual inflectional feature being set, for example
* <code>LexicalFeature.PRESENT_3S</code>
* @param form
* the actual inflected word form
