spring:message inside a meta content argument

Hi there

Im trying to fill the content argument of a meta tag inside a site, dynamically.

example:

HTML Code:

---

<meta name="description" content="<spring:message code="${page.metaDescriptionKey}" />">

---

This produces the error:

Code:

---

The value of attribute "content" associated with an element type "null" must not contain the '<' character.

---

Surely this comes from using a spring tag inside the argument but how would you solve this? I want to keep the content language-dynamic.

Thanks for any hints

Problem stills exists. Anyone?
