XSD Pattern restriction. How to get a shorthand

I have an XSD grammar where one SimpleType which should be restricted to a 6 comma-separated numeric values. That is, each element is of the form:

-?\d*\.?\d+\s*

As I need a 6-tuple I can write the following pattern:

<xs:pattern value="-?\d*\.?\d+\s*,\s*-?\d*\.?\d+\s*,\s*-?\d*\.?\d+\s*,\s*-?\d*\.?\d+\s*,\s*-?\d*\.?\d+\s*,\s*-?\d*\.?\d+\s*"/>

I wanted to short it. I've tried with the following pattern:

<xs:pattern value="(-?\d*\.?\d+\s*,){5}\s*-?\d*\.?\d+\s*" />

But seems to be wrong. I cannot recognise the error. Can anybody tell me why is this wrong?

Thanks in advance

In what way does it fail?

It works for me (with Saxon as the schema validator). With the schema

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:saxon="http://saxon.sf.net/">
  <xs:element name="top">
    <xs:simpleType>
      <xs:restriction base="xs:string">
        <xs:pattern value="(-?\d*\.?\d+\s*,){5}\s*-?\d*\.?\d+\s*" />
      </xs:restriction>
    </xs:simpleType>
  </xs:element>
</xs:schema>

this document is valid:

<top>1,2,3,4,5,6</top>

and this one is invalid:

<top>1,2,3,4,5</top>
