The version of XML is irrelevant for this.
I was wondering if 1.0 element names need escaping at all.
But the text certainly will.

So I think you want a stylesheet that specifies xsl:output
method="text".

Then a template somthing like:

<xsl:template match="/">
data:text/html;charset=US-ASCII;base64,<xsl:apply-templates/>
</xsl:template

Then in subsequent templates write out the base64 encoding (you can
write an xsl:function for this) of each node.

Alternatively, you can omit the base64, and %encode everything with
escape-html-uri (if that's the right function for the data URI
scheme. (The RFC says:

"without ";base64", the data (as a sequence of
   octets) is represented using ASCII encoding for octets inside the
   range of safe URL characters and using the standard %xx hex encoding
   of URLs for octets outside that range."
