[xsl] what is ....select=3D" ..... ???

[Detlef Heyn <detlef.heyn@xxxxxxxxx>]

Hi there,


just a simple question about this random code snippet from the mailing list.

between   'select='   an  '"......."' i always found this "3D".

example quote:
==============
<xsl:apply-templates select=3D"/*/*/*" >
        <xsl:sort select=3D"@GroupNumber" />
        <xsl:sort select=3D"@ElementNumber" />
</xsl:apply-templates>
==============


Please could someone be so kind to tell me, is it just a character 
coding error or is it something new in XSLT2.0 wich I just did not 
recognized yet?

Searched for it without any satisfyingly result.


Probably a totaly trivial question - so forgive my unawareness about 
this "3D" Prefix - but i some clearing about it.

Thanks for your help in advance.


with best regards

D.H.H.
