PR #2259: 938 Canonical serialization

Pull request #2259 by Arithmeticus.

This represents a first draft to resolve issue #938 (and thereby slightly reduce our workload). Because both JSON and XML have canonical specifications, and there is nothing barring canonicalization being imposed upon other methods, I have opted to introduce the serialization parameter `canonical` as a boolean, rather than extend the number of method options. I had to make certain decisions in this first draft, worth discussing. * The CX1.1 specs permit a parameter on whether to keep comments or not -- I think the user should deal with that before trying to serialize. * I opted not to specify what happens for escape-solidus, use-character-maps, normalization-form and some other options, where user control may be desired. * When a JSON object has an XNode, and when canonical is yes, I think the current serialization parameters should propagate down to the sub-serialization process. * I think the normalization step I added to 4 Serialization may not be necessary, or incorrectly conceived. * I opted to avoid specifying exactly what changes should be made to the JSON or XML, deferring to the external specifications. In line with that, I attempted to treat canonicalization as an encapsulated postprocess that could be cleanly disentangled from all the other options involved in serialization. I've tried to make patches everywhere relevant, but I'm guessing there are places I've overlooked. Comments welcome.

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 #2213: 2047 External resources and security

Pull request #2213 by michaelhkay.

Fix #2047 This is a first draft of a PR that is intended to provide a framework for controlling the trust level for applications to access external resources. Although this is still at draft status, comments are solicited on the general approach.

PR #2205: 2190 Drop binary input for parse-csv and parse-json

Pull request #2205 by michaelhkay.

This PR reverts the change to parse-csv() and parse-json() allowing them to take binary input. The change was made primarily for consistency with parse-xml() and parse-html(). However, those functions have a legitimate reason to accept binary input, because discerning the encoding may be intermingled with parsing in the case of input documents that use custom syntax to define their own encoding. This is not the case for CSV and JSON, where standard decoding tools may be used. In addition, there was no good reason to add the option to parse-csv() and not to csv-to-arrays() or csv-to-xml().

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.
