This release adds an option to specify the culture used to parse patterns in the isDateTime placeholder.

Full list of changes:

• IsDateTimePlaceholderHandler now supports an optional second argument specifying a
  different CultureInfo than the invariant culture used by default as
  CultureInfo name like de or fr-FR.

  Also modified the logic when no argument is present to still try
  parsing using the current culture and then trying a set of ISO
  patterns using the invariant culture in turn - making isDateTime
  match what the Java version does mor closely.

• placeholders can now also be used inside of the local part of xsi:type attributes.
  PR #49

• PlaceholderDifferenceEvaluator would cause InvalidCastException for documents with
  differences in xsi:type attributes.
  Equivalent of XMLUnit Java Issue #xmlunit/276

• added readme files for the nuget packages.
  Issue #46.

• the NUnit 4.x constraints package tags nunit3 rather than nunit4.
  PR #43.

• added Cyclone DX SBOMs to release artifacts
  Issue #47.

• introduced a new constraints library for NUnit 4.x as the NUnit 3.x
  constraints can not be used with NUnit 4.x at all.
  Issue #42.

• adjusted the NUnit 3.x constraints so they should work for NUnit 4.x as well.
  Issue #40.

• add a new ElementSelectors.ByNameAndAllAttributes variant that filters attributes before deciding whether elements can be compared.
  Inspired by Issue #xmlunit/259

• Nodes.GetMergedNestedText and Nodes.StripElementContentWhitespace had the same problem of not knowning about XmlWhitespace that caused Issue #38. And neither of the methods could deal with XmlSignificantWhitespace at all.

• add XmlWhitespaceStrippedSource, XmlWhitespaceNormalizedSource, and XmlElementContentWhitespaceStrippedSource that only trim characters that are considered whitespace by the XML Specification from textual content.
  Also added new modifiers to DiffBuilder that make use of the new ISource types.
  Issue #39.

This is a small feature and bugfix release.

The full changelog is

• added NodeFilters#SatisfiesAll and SatifiesAny methods to make it easier to combine multiple node filters.
  added to simplify the use case of xmlunit/#249

• when documents contained element content whitespace represented by System.Xml.XmlWhitespace the types and methods that are supposed to strip or normalize whitespace would fail.
  Issue #38

XMLUnit.NET ports changes made to XMLUnit for Java 2.8.3 and 2.8.4. The full changelog is:

• improved comparison performance for documents with many siblings
  based on a suggestion by @gerpres made in Java Issue xmlunit/#236

• added a new FullDescription method to Diff that provides a string-representation of all differences - not just the first one like ToString does.
  Based on Java PR xmlunit/#235 by @Boiarshinov

This release fixes a bug for a very specific setup and makes ISource disposable.

Full details:

• ISource now extends IDisposable to allow releasing unmanaged resources used when building sources from files or URIs.

  This change is backwards incompatible if you are providing ISource implementations of your own.
  #33.

• DefaultNodeMatcher with multiple ElementSelectors could fail to find the best matches as the order of ElementSelectors should select them.

This version contains a backwards incompatible change to the IPlaceholderHandler interface that is part of the experimental placeholders module: The Evaluate method now receives a variable number of string arguments in addition to the textual content of the element/attribute. This allows placeholders like ${xmlunit.matchesRegex(some\s*regex)}.

Only the placeholder package has been changed, all other packages are functionally identical to XMLUnit.NET 2.7.2.

This release fixes a bug in the construction of XPaths in certain corner cases:

• the XPath values for comparisons resulting in CHILD_LOOKUP
  differences could be wrong when NodeFilters were present.
  Issue #29

The release fixes a bug in a corner-case and adds a new isNumber placeholder.

• add a new ${xmlunit.isNumber} placeholder
  Based on the Java PR xmlunit/#154 by @NathanAtClarity.

• the XPath values of a comparison should not be affected by any NodeFilter being in effect.
