Abbreviated Syntax

Hello. I´m begginer about XSL and I´m using Coocon 1.5. I want Know why
some of the Abbreviated Syntax commands don´t work in Cocoon. For
example:

<xsl:template match="/">
<xsl:apply-templates select="//CCC"/>
</xsl:template>

Cocoon does not recognize // CCC .When I try to execute my XML document
by
Cocoon I only can see one white page. So no action is performed and no
errors are reported.I tried using another commands instead of //CCC and
Cocoon works. So my XML and XSL documents are well-formed.

I have the same problems with commands like child::*

 Where can I found all commands
supported by Cocoon?

 Thank you
