[ANN] First Pre-Release of VSCode Extension for XSLT

Dear list,

We're pleased to announce the first pre-release of XPath-Embedded, an
extension for the VSCode. The initial focus is on providing XSLT
language features for this popular code editor.

XPath-Embedded is an open-source project managed by DeltaXML. Here are
the base features for this early-stage project:

- XSLT 3.0 / XPath 3.1 Syntax Highlighter
    - Single-pass character-by-character lexer for performance/accuracy
    - Support for proposed XSLT 4.0 additions implemented in Saxon 10.0
          (see: http://www.saxonica.com/papers/xmlprague-2020mhk.pdf)
- XSLT and XPath code-formatting:
    - Format As-You-Type
    - Format Document
    - Format Selection
    - Format On Paste
- Integration through VSCode Tasks with the Saxon XSLT Processor (9.9 or later)
     - Compile-time or run-time warnings/errors highlighted in the code
     - Navigate errors/warnings via the Problems Pane
     - Tasks allow multiple configurations of xsl:param settings etc.
