Commas in DocumentFormat.OpenXml.Wordprocessing.Name.Val property cause invalid value error

**Describe the bug**

According to the "data\SchematronFiles\word.xml" lines 3618 - 3628 the `w:val` property for the `w:name` element should be invalid if it contains a comma only for `w:name` elements that are children of `w:category` or `w:fieldMapData`, but the `CollectSchematronItems` method from "tools\SemanticConstraintRegGen\SchematronDataProvider.cs" line 66 splits the `Context` on `/` leaving only the property name instead of the full path. So, in schematron.json the restriction becomes:

```json
{
"Context": "w:name",
"Test": "matches(@w:val, \u0022[^,]*\u0022)",
"App": "Word"
},
```
restricting the `w:name` property from containing commas for all elements in Word.

This may be a "won't fix", because it looks like it will either be a major rewrite of how that validation works that could involve breaking changes or creating separate classes for the different `w:name` elements, like `FieldMapDataName` and `CategoryName`, but this would definitely be a breaking change as they all currently use `DocumentFormat.OpenXml.Wordprocessing.Name` for this class. I'm adding the issue in the hope I'm wrong.

**To Reproduce**

Add commas to the `w:val` property of a `w:name` element that is not the child of `w:fieldMapData` or `w:category` (e.g. `w:docPartPr` or `w:style`) then create an instance of the `OpenXmlValidator` and validate the file.

**Observed behavior**

The validator returns an invalid value error for the `w:val` property.

**Expected behavior**

Expected the validation to pass without error.
