[daisy] Accessing a document's fields / reading the whole XML tree

[A Rocha Webmaster]

Hello all,

= First question =

I am trying to access a field. I've added a Description text field to
the Attachment document; and now I want the Attachment HTML page to show
that value in a meta name="description" field.

http://cocoondev.org/daisydocs-2_1/374-cd/25-cd/190-cd.html

The above does not indicate any fields. Don't I have access to the
document's fields in the layout.xsl input contract?

I see that the fields are mentioned here --
http://cocoondev.org/daisydocs-2_1/374-cd/g1/26-cd.html
but this is *not* where I want to access them.

Help, please?

= Second question =

Is there a URI for the input contract? I want to be able to read the
output of the whole XML document given a doc ID, *before* any XLST
transformations. That would really help with the Daisy learning curve.
If there isn't a URI, can I fetch the XML in any way? I tried

<xsl:comment><xsl:copy-of select="."/></xsl:comment>

but no luck.

More help, please?

Júlio.
