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

[Hugh Cayless]

Yeah, that can’t be right. I think we should assume the @match XPath relies on the namespace declarations available in its context. If we *wanted* to use that prefix, I think the example would have to be something like:

> <certainty xmlns:tei="http://www.tei-c.org/ns/1.0" match="parent::tei:gap/@reason"
> locus="value" cert="low"/>

(or to make clear that the tei prefix had been declared on some ancestor element). It’s not a great XPath anyway…wouldn’t ../@reason be more idiomatic?

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?
