Subject: [xsl] XSLT 3.0: The definition of the "unnamed mode" From: "Dimitre Novatchev dnovatchev@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Sat, 27 Dec 2014 19:05:12 -0000 |
In the 2nd Last Call of the W3C XSLT 3.0 specification, section "6.6.1 Declaring Modes" defines "unnamed mode" thus: "[Definition: The unnamed mode is the default mode used when no mode attribute is specified on an xsl:apply-templates instruction or xsl:template declaration, unless a different default mode has been specified using the [xsl:]default-mode attribute of a containing element.]" I find this definition rather confusing, because the undefined term "default mode" is used and because this term seems undistinguishable from two other terms used in the definition: "different default mode" and "[xsl:]default-mode attribute". To summarize, this definition seems (endless) recursive, having not specified the term "default mode" on which it is based. I believe that a definition that more precisely defines the "unnamed mode" could be something like this: 1. A mode defined in an xsl:mode declaration (the one with highest import precedence) that has no "name" attribute specified, or 2. If there is no xsl:mode without a "name" attribute, then a mode that is defined by an (implicit) xsl:mode declaration without any attributes. 3. The unnamed mode defined in 1. and 2. above is used as the value of the "mode" attribute of any "xsl:template" or "xsl:apply-templates" that have no "mode" attribute specified, unless these are in the scope of an "[xsl:]default-mode" attribute, in which case the mode specified in the (innermost) "[xsl:]default-mode" attribute is used as the value for their "mode" attribute. Any thoughts, please? -- Cheers, Dimitre Novatchev
