Use MathML intent to disambiguate coordinate pairs

[abcdsen-create]

Priority: Medium

Description

Document
how to distinguish a coordinate pair such as (1, 2) from an open interval or a
generic parenthesized pair. When the authoring and reading systems support
MathML intent, mark the semantic role explicitly and identify the coordinate
arguments with arg.

Recommended markup

<mrow
intent="coordinate($x,$y)">

<mo>(</mo><mn
arg="x">1</mn><mo>,</mo><mn
arg="y">2</mn><mo>)</mo>

</mrow>

Acceptance criteria

• Guidance explains why the visible symbols alone are ambiguous.
• A coordinate example uses intent and matching arg values.
• Expected behavior is tested in each supported reading system.
• Unsupported systems or authoring tools are documented, with a defined fallback or review workflow.

Reading-pipeline dependency

Confirm
that the target reader and speech-rule engine support this intent vocabulary.
If not, track implementation as a separate software issue.
