15:05:02 <Norm> Topic: Accept this agenda?
15:05:02 <Norm> -> http://www.w3.org/XML/XProc/2015/02/04-agenda
15:05:13 <Norm> Accepted.
15:05:16 <Norm> Topic: Accept minutes from the previous meeting?
15:05:16 <Norm> -> http://www.w3.org/XML/XProc/2015/01/28-minutes
15:05:22 <Norm> Accepted.
15:05:29 <Norm> Topic: Next meeting
15:05:50 <Norm> I propose 25 Feb for our next telcon.
15:06:05 <Norm> No regrets heard.
15:06:34 <Norm> Topic: Do we need p:import-schema
15:06:45 <Norm> ->
15:06:48 <Norm> -> https://github.com/xproc/specification/issues/92
15:06:54 <Norm> Norm sets the stage...
15:08:18 <Norm> Loren: It would be nice to have, but it could be very hard to implement.
15:08:24 <Norm> Norm: I think we'd have to make it optional.
15:10:00 <Norm> Henry: I think it would be good if we could do this in a way that operates by only forwarding the relevant information to the places that need it.
15:10:25 <Norm> ...I think it would be good if we didn't have to implement schema processing to be an XProc 2.0 processor.
15:11:43 <ht> so that's select="..." as="...", not select="... as ..."
15:11:45 <Norm> Norm: I think it only bites us where we have sequence types in "as=" attributes.
15:11:45 <ht> Right?
15:11:50 <ht> Yes
15:11:55 <Norm> Henry, yes.
15:12:33 <Norm> <p:variable name="hatsize" select="$param - 4" as="my:hatsize"/>
15:12:43 <Norm> <p:variable name="hatsize" select="$param - 4" as="xs:integer"/>
15:13:43 <Norm> Henry: What are our obligations under the latter? Is all that we have to do with this is record it?
15:13:48 <Norm> Norm: No, I believe we have to validate it.
15:14:38 <ht> <p:variable name="hatsize" select="($param - 4) as xs:integer"/>
15:15:49 <ht> if (@x castable as xs:date)
15:16:06 <Norm> (4 as xs:integer) + 3
15:17:14 <Norm> <xsl:variable name="fred" select="(4 - 2) as xs:integer"/>
15:17:22 <Norm> Norm: That doesn't work "as" isn't allowed there.
15:17:43 <ht> "2003-02-28" cast as xs:date
15:17:52 <Norm> <xsl:variable name="fred" select="(4-2)" as="xs:integer"/> is the same as let $fred = (4-2) as xs:intger
15:18:15 <Norm> s/intger/integer/
15:18:51 <Norm> Henry: Given that "cast as" does work, I'd like to explore the possibility that we say not just in spec prose but that we define select=x as=y as "x cast as y"
15:19:17 <Norm> ...Then import schema is just something that defines the static context, it doesn't cost us anything.
15:19:24 <Norm> s/context/context for XPath evaluation/
15:19:40 <jfuller> same thing with constructor func
15:19:42 <jfuller> eg usa:zipcode("12345")
15:20:23 <jfuller>  ("12345" cast as usa:zipcode?).
15:20:23 <Norm> Henry: I don't know if constructor functions work for user-defined types.
15:20:30 <Norm> Jim: It's equivalent to the cast as expression.
15:21:26 <Norm> Henry: It also pushes the error handling off to the substrate, which is just fine.
15:22:13 <Norm> Norm: We should think about this. "as" and "cast as" aren't the same, so we should know what the differences are.
15:23:21 <Norm> Henry: It seems to me that we need import schema even if we don't use them in as= attributes. We want users to be able to write usa:zipcode in their XPath expressions.
15:24:17 <jfuller> http://www.w3.org/TR/xpath-30/#id-schema-import-processing
15:24:24 <jfuller> seems to align with leaving it to the host language
15:25:22 <Norm> Norm and Henry speculate about the Saxon API.
15:26:10 <Norm> Topic: Should we adopt shadow attributes?
15:26:15 <Norm> -> https://github.com/xproc/specification/issues/78
15:26:32 <Norm> Norm explains: http://www.w3.org/TR/xslt-30/#shadow-attributes
15:27:09 <Norm> Henry: Quoting from XSLT 2.0 if the "as" attribute is supplied then the value is converted to the required type.
15:27:13 <Norm> Norm: So that is cast as.
15:27:24 <Norm> Henry: That's on xsl:param, we need xsl:variable.
15:30:14 <Norm> Norm: The question of whether or not xsl:params are in scope is an interesting one.
15:31:04 <Norm> Henry: Not at the sub-pipeline level, p:libraries have to be compiled separately.
15:31:48 <Norm> Henry: I remember distinctly trying to do that with the document type attribute on the xslt:output statement. The fact that you can't compute the doctype that you want your output to have is very annoying.
15:33:34 <ht> I guess I think that's a vnext.1 feature
15:33:54 <Norm> Jim: I'm not so enthusiastic.
15:34:29 <Norm> Norm: Sounds like there isn't enthusiasm. Shall we decline this issue?
15:34:36 <ht> I'd like to see that works for XSLT before committing
15:34:43 <ht> s/that/how that/
15:35:06 <ht> s/works/works in practice/
15:35:23 <Norm> Jim: I don't think we need to drop it, but I think we should have some more time to think about it.
15:35:49 <Norm> Norm: Ok, I'll leave it open for now.
15:36:15 <Norm> Topic: Any other business?
15:36:23 <Norm> None heard.
15:36:48 <Norm> Adjourned.
