[tei-council] tei: prefix in @match attribute

[Martin Holmes]

Hi all,

This example:

<certainty match="parent::tei:gap/@reason"
 locus="value" cert="low"/>

which appears in this spec:

<http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ref-certainty.html>

uses a tei: prefix in the @match attribute, to point to the parent element. Why does it do that? Do we assume that the default element namespace in the XML document is not inherited by the XPath context for the match expression? Even if that's the case, doesn't it require that a tei: prefix be defined somewhere before it can be used?

Cheers,
Martin
