NoClrMapping Extension for Input Fields with Custom CLR Mapping (from version 8.4.0)</h3>
+<p>A new extension method, <code class="language-text">NoClrMapping</code>, has been introduced to give you fine-grained control
+over how input object fields are mapped to CLR types. In many scenarios, your input types may
+include fields that are computed or require custom processing before being set on your CLR model.
+For example, you might have a CLR type with a single <code class="language-text">FullName</code> property but want your input
+object to accept separate <code class="language-text">firstName</code> and <code class="language-text">lastName</code> fields. By marking these fields with
+<code class="language-text">NoClrMapping()</code>, they are excluded from the automatic binding process. You can then override
+the <code class="language-text">ParseDictionary</code> method to manually combine these values into the CLR's <code class="language-text">FullName</code> property,
+while letting the base implementation handle any automatically mapped fields (such as <code class="language-text">Age</code>). The
+following example illustrates this pattern:</p>

+<p>In this example, the input object defines three fields: <code class="language-text">firstName</code>, <code class="language-text">lastName</code>, and <code class="language-text">age</code>.
+The <code class="language-text">firstName</code> and <code class="language-text">lastName</code> fields are marked with <code class="language-text">NoClrMapping()</code> so that they are not
+automatically bound to any CLR properties. Instead, the overridden <code class="language-text">ParseDictionary</code> method
+combines these two fields into the <code class="language-text">FullName</code> property of the <code class="language-text">Person</code> CLR type. Meanwhile,
+the <code class="language-text">Age</code> field is processed via the standard mapping mechanism by calling <code class="language-text">base.ParseDictionary</code>.
+This approach allows you to seamlessly mix automatic and custom binding, providing greater
+flexibility in how your input objects are processed and mapped.</p>
