+### body-only-if
+
+If you find that you have a wrapper element that is conditional, but whose body should always be rendered then you can use the `body-only-if` attribute to handle this use case. For example, to only render a wrapping `<a>` tag if there is a valid URL then you could do the following:
+
+```html
+<a href="${data.linkUrl}" body-only-if="!data.linkUrl">
+    Some body content
+</a>
+```
+
+Given a value of `"http://localhost/"` for the `data.linkUrl` variable: , the output would be the following:
+
+```html
+<a href="http://localhost/">
+    Some body content
+</a>
+```
+
+Given a value of `undefined` for the `data.linkUrl` variable: , the output would be the following:
+
+```html
+Some body content
+```
