Summary

Replace the last four exact XML placeholders in Android.Graphics.Pdf.Models.Selection: the summary and remarks of the explicit Java.Interop.IJavaPeerable.UnregisterFromRuntime implementation in PageSelection.xml and SelectionBoundary.xml.

Both members declare M:Java.Interop.IJavaPeerable.UnregisterFromRuntime in their Implements metadata. The summaries use the canonical contract: unregistering prevents future JniValueManager.PeekValue calls from returning the instance. The remarks identify the explicit interface implementation and how to call it.

Sources:

• Existing canonical documentation: docs\xml\Java.Interop\IJavaPeerable.xml, member UnregisterFromRuntime.
• Microsoft Learn: IJavaPeerable.UnregisterFromRuntime.

These are .NET-only interface implementations, so no Android/Java importer or Java mapping is used. Existing documentation, API metadata, attribution, and file formatting are unchanged.

Verification

Full scan of docs\xml\Android.Graphics.Pdf.Models.Selection plus docs\xml\ns-Android.Graphics.Pdf.Models.Selection.xml, excluding generated index/filter/framework files:

File	Before	After
PageSelection.xml	2	0
SelectionBoundary.xml	2	0
PageSelection+InterfaceConsts.xml	0	0
SelectionBoundary+InterfaceConsts.xml	0	0
ns-Android.Graphics.Pdf.Models.Selection.xml	0	0
Exact XML placeholders	4	0

Exact placeholder counts use XML elements whose entire text is To be added. rather than substring matches. Phrase matches also decreased from 4 to 0. Legitimate non-placeholder phrase matches: 0 before and 0 after.

All five XML files parse. A comparison against the base confirms that only the four placeholder elements changed. git diff --check and the committed diff check pass.

Fixes: #112

The full issue scope has zero actual placeholders in this change. The closing reference takes effect when the PR is merged; the local count alone is not a completed merge.

What changed in this PR

Completes the four remaining documentation placeholders in Android.Graphics.Pdf.Models.Selection by documenting the .NET-only UnregisterFromRuntime implementations.

Changes:

• Adds summaries describing the canonical runtime-unregistration contract.
• Adds remarks explaining explicit interface implementation and how to call the members.
• Leaves API metadata and existing documentation unchanged.

File	Description

[dalexsoto]

The four explicit runtime-unregistration placeholders match the canonical IJavaPeerable contract and exact DocIds, while the complete namespace scope and surrounding API metadata are preserved.

Source-only documentation and static integration review; no converter or installed-runtime execution is claimed.
