string to number casting in Xalan 2.2

A statement like <xsl:value-of select="number('1.23E1')"/> produces '12.3'
in Xalan 2.1, and 'NaN' in 2.2.

The difference is caused by how XString cast string to number,
In 2.1, it's done by calling Double.valueOf(),
In 2.2, it's done by a hand crafted parsing routine that returns
        NaN when encounters a non-digit char.

The behavior in 2.2 is not standard compliant. Please fix. Thanks.
