What I did with spring-data-jpa-1.3 was adding a version to xsd and lowered it to 1.2. Then the error message disappears. Like this
<beans
xmlns="http://www.springframework.org/schema/beans"
...
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
...
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa-1.2.xsd">
Seems like it was fixed for for 1.2 but then appears again in 1.3.
