Changes

Initial work on creating an index

Say 'escape sequence', not 'escape code'

Although both terms seems to be in use, 'escape sequence' seems to be the more generally recognized one.

Add \firstuse terms to index

Rephrase introduction to chapter 'Annotations', with index entry for 'annotation'

Consistent white-space around 'annotation'

Use math instead of semi-inline code style for coordinates

Add 'assert' and 'terminate' to index

Add 'return', 'break', 'nondiscrete'

Fix remaining cases of 'restricted class' -> 'specialized class'

Add keywords for specialized classes and inheritance

Describe 'encapsulated' and add to index

Add built-in scalar types

Add some missing language=grammar

Describe 'partial' in text and add to index

Add remaining keywords

Add built-in types

Add operators, functions, and a few annotations

Rename command \indexinline -> \robustinline

Add annotations

Add some mathematical terms

Add attributes of built-in types

More use of \indexinline and move indexing commands after listings

Migrate glossary terms on 'A'

Migrate more terms from glossary

Some use of \ldots in listings

Don't use 'subclass' in favor of 'derived class'

Add simple assignment statement to index

Add more terms from glossary

Drop 'variability' from glossary (already present in index)

Migrate 'component reference' to index

Drop useless mention of 'declaration assignment'

Since the sentence already speaks of binding equations in general, there is no need to say that it also covers binding equations in functions (which is what 'declaration assignment' is supposed to have meant).

Migrate 'declaration equation (deprecated)' to index

Migrate 'element' to index

Migrate 'extends clause' to index as 'extends-clause'

Migrate 'modification' and related terms

Dropping 'encapsulated' from glossary in favor of indexed keyword

Move explanation of 'equation' to chapter introduction

Migrate 'event' and 'expression'

Migrate remaining glossary entries

Remove empty glossary

Add comment with suggestions for more terms to define in introduction

Remove odd emphasis on 'quality of implementation'

Remove broken symbolic link to removed glossary

Basic HTML styling of document index

Add 'Modelica URI scheme' to index

Add clocked variables in DAE-chapter.
Just the minimal so that they don't look totally forgotten.
Closes #2286

Allow end for non-integer indexing.
Closes #2204

Always use dashed form 'base-clock partition'

Remove \emph on non-first use of 'clock inference'

Besides not being a first use, it seems like we are generally not using \emph or \willintroduce in this introductory section.

Define that disabled conditional components are ignored.
Closes #2499

Group index entries under 'clock' and 'clocked'

Use non-normative mention of 'connector' as main index entry

Put 'algorithm section' under 'algorithm'

Group terms under 'array'

Group terms under 'continuous-time'

Group terms under 'component'

Add test-case annotation. (#2764)

* Add test-case annotation.
Was a bit unclear how to include it, but think adding it close to experiment was best and with minimal impact on index.
Closes #2340
* Apply suggestions from code review
Co-authored-by: Henrik Tidefelt <henrikt@wolfram.com>

Simplify description of input/output for functions.
Closes #2730

Add exception for encapsulated short class lookup (#2759)

* Add exception for encapsulated short class lookup, and example demonstrating it.
Closes #2743

Clarify that a clock cannot be input to hold. (#2773)

Closes #2174

Specify Evaluate for hierarchical components. (#2771)

* Specify Evaluate for hierarchical components.
Closes #2288

Clarify heterogenous array of records. (#2769)

* Clarify heterogenous array of records.
Closes #2282

Improve formulation of rational clock. (#2763)

* Improve formulation of rational clock.
It might be that we should have a clearer separator for the =0 case.
Closes #2386

Fix case of fixed parameter without declaration equation

Change input points to const for C. (#2767)

* Change input points to const for C.
Closes #1955

State that external object class is a class. (#2760)

* State that external object class is a class.
Closes #2705

Fix link to undefined label 'array'

Slightly modify example on prevention of external function evaluation
