PR #2313: 2298 XQFO rules: definition of default values

Pull request #2313 by ChristianGruen.

@michaelhkay I have decided to create this PR, even if we are still discussing its necessity. I hope it clarifies where I see the need for unifications in the current presentation. In general, it follows the proposal that I developed in my thoughts in #2298. In particular, it fixes various small inconsistencies in the prose. I have stumbled upon related editorial issues that I haven’t worked at yet: [1.6 Function calls](https://qt4cg.org/specifications/xpath-functions-40/Overview.html#id-function-calls) is outdated, for example the `fn:function-name` (which could be confused with the actually existing function with the same name) should have an optional parameter. Next, the text talks about “two signatures of `fn:string`”; and it is not clear why the “zero or one values” and “zero or more values” cases are presented in more detail, whereas “one or more” is missing. The reason is probably simple: It seems to stem back to version 3.1. Closes #2298

PR #2309: Allow SimpleMapExpr after ArrowExpr

Pull request #2309 by ruv.

Fix #2299 Allow the form `A => B() ! C` and make it equivalent to `( A => B() ) ! C`. Also, allow all operators from `PostfixExpr` in the same manner.

PR #2301: 2198 Add cdata attribute to xsl:text and xsl:value-of

Pull request #2301 by michaelhkay.

Allow xsl:text and xsl:value-of to request serialization of the content as a CDATA section.

PR #2283: 2276 Relax XSLT rules on Extension Attributes

Pull request #2283 by michaelhkay.

Changes the rule for extension attributes, instead of saying they MUST NOT cause non-conformant behaviour, we now say SHOULD NOT, and give examples where it might be appropriate to break this rule, e.g. for security. Also, extension attributes can now modify the behaviour of the serializer in any way they like. The PR also moves the section on Extension Attributes to a more logical place in the spec.

PR #2282: 2278 Add function bin:infer-encoding; simplify bin:decode-string

Pull request #2282 by michaelhkay.

This PR separates the operation of examining a string to determine its encoding and the presence of a BOM, from the operation of decoding octets. The purpose is to simplify the decode-string function and to reduce complex interactions between its arguments, especially in cases where the BOM might be at the start of a message and the strings to be decoded at some later position. It also has a better chance of retaining compatibility with 1.0 implementations (though it's hard to guarantee that since 1.0 was underspecified).

PR #2281: 2280 Usability of xsl:array-member

Pull request #2281 by michaelhkay.

Fix #2280 This PR revises the spec of xsl:array and xsl:array-member in the light of experience writing test cases. The zero-arity function item constructed by `xsl:array-member` now carries a function annotation which means that it can be unambiguously recognized as having been so constructed. This allows better error checking and diagnostics, and it also allows `xsl:array` to be more tolerant of using `xsl:array-member` to create singleton array members in circumstances where it is not strictly required.

PR #2256: 2216 All atomic types become ordered

Pull request #2256 by michaelhkay.

This is work in progress, pushing it mainly so I can review the diffs. The first benefit is that nearly all comparisons can now be described by reference to `compare(A, B) = 0`.

PR #2247: Deferred Evaluation in XPath - the f:generator record

Pull request #2247 by dnovatchev.

This PR introduces the notion of deferred evaluation and presents the tool to achieve this - the built-in named record type `f:generator`. - Two major use cases are presented. - The fields of `f:generator` are defined. - All system-provided methods of `f:generator` are defined. - Examples of using each of the methods of `f:generator` are provided. - The formal equivalents of each of the system-provided methods of `f:generator` are provided in a separate appendix. <img width="1920" height="1080" alt="image" src="https://github.com/user-attachments/assets/65d04952-794f-4a81-ae64-c96217a9812d" />

PR #2160: 2073 data model changes for JNodes and Sequences

Pull request #2160 by michaelhkay.

This is a first draft of a PR, giving the data model changes only, for a change to the JNode model affecting maps and arrays with sequence-valued entries. A sequence of length 2 or more now has children representing the items in the sequence. Although there is still an asymmetry between sequences of length 1 and longer sequences, it is more manageable than i the previous model.

PR #2124: 573 Functions to Construct Trees

Pull request #2124 by michaelhkay.

A first cut at providing a functional approach to XNode and XTree construction. At this stage I'm interested in comments on the general approach, not the fine detail (some of which, e.g. namespace inheritance, still needs work.)

PR #2071: 77c deep update

Pull request #2071 by michaelhkay.

Proposes a new fn:update function that can handle both JNodes and XNodes. (this is a branch on a branch, so I don't know how well the diff'ing will work; but look in F&O for the fn:update function)

PR #2019: 1776: XSLT template rules for maps and array

Pull request #2019 by michaelhkay.

Currently work In progress, committed so that the draft can be reviewed. Changes in three main areas: - Pattern syntax: patterns such as `?item` and `?parent?item` are defined to match items in a map by their key - Built-in template rules for on-no-match="shallow-copy-all". Revisits the built in template rules for this scenario. - General revision of the processing model for xsl:apply-templates applied to a tree of maps and arrays.
